Experimental Questions 1- Which types of compounds have the strongest.docx
Experimental Questions 1. Which types of compounds have the strongest intermolecular forces? How can certain physical properties give an indication of the strength of intermolecular forces of compounds? 2. 3. Relate molecular polarity to the intermolecular forces of the molecule. 4. Relate intermolecular forces of the molecule to physical properties such as evaporation and viscosity.
Solution
1. The strongest intermolecular force is hydrogen bonding. Thus the compounds that can form H- bonds each other have the strongest intermolecular forces.
2. When intermolecular forces increases the molecules fells greater attraction among themselves. This means we have to supply more energy to separate them. This result in higher in the physical property. Thus if stronger intermolecular forces are existing we can expect that boiling point , melting point for that sample will increase. Again in case of freezing we have to restrict the movements of the molecules.Thus when stronger forces are there there are already some restriction in the movements and so freezing point is higher. In other words we can say that molecules where there is lower intermolecular forces we have to lower the temperature more to freeze it.
3. When polarity of the molecules increases this gives greater intermolecular forces and thus higher physical properties. This is because each molecular dipole allign themselves with others in such. a way that
(+)vely charged part attract the (-)vely charged part and this result long range intermolecular forces. This gives higher intermolecular forces.
4. Evaporation means escape of molecules from the liquis phase. When there is strong intermolecular force exists this means the molecules attract each other more. Thus escape from liquid phase is less. But when intermolecular force is weaker then molecules can escape easily. This means lower the intermolecular force higher the evaporation rate.
Again Viscosity is the resistance of a liquid to flow. When attraction is more among the molecules they resist the flow of other molecules. This implies higher viscosity. For example ethanol , CH3CH2OH, has the viscosity 1.07 mPa.s and ethylene glycol, HOCH2CH2OH , has 16.2 mPa.s. We can see that in case of ethanol there is only one OH group. But in case of ethylene glycol there is 2 OH group that can form strong H bonding. This results higher attraction among ethylene glycol moecules and so higher viscosity.

Physical Science 12 POLARITY OF A MOLECULE TO ITS PROPERTIES.pptx
Polarity relates to physical properties like solubility, melting and boiling points through intermolecular forces of attraction. Polar molecules interact strongly through hydrogen bonding and dipole-dipole interactions, giving them higher melting and boiling points. Nonpolar molecules have weaker London dispersion forces and lower melting and boiling points as a result.
Liquid
Liquids have molecules that are close together and experience stronger attractive forces than gases, allowing them to flow freely within a container but take its shape. Viscosity, a liquid's resistance to flow, depends on molecular size and intermolecular forces, and increases for more complex, polar molecules. Surface tension results from attractive forces between liquid molecules and causes the surface to contract, while vaporization occurs when high-energy molecules overcome attractive forces and escape as a gas. Vapour pressure is affected by intermolecular forces and temperature, increasing with weaker forces and higher temperatures.

ESR spectroscopy in liquid food and beverages.pptx
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.
Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.
The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptx
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.

Deep Software Variability and Frictionless Reproducibility
Deep Software Variability and Frictionless ReproducibilityUniversity of Rennes, INSA Rennes, Inria/IRISA, CNRS
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

- 2. Different properties dependent on intermolecular forces. Phase at room temperature When molecules have strong intermolecular forces of attraction, they are packed close together. They often exist as condensed phase (solid or liquid) at room temperature. When molecules have weak intermolecular forces of attraction, they are far apart from each other. They often exist as gas at room temperature.
- 3. Solubility Solubility refers to the ability of a substance to dissolve in a given amount of solvent at a specified temperature. Recall the rule “like dissolves like.” When the solute and the solvent both exhibit the same intermolecular forces of attraction, they form a solution.
- 4. Melting point and Boiling point If molecules stick together more, they'll be tougher to break apart Stronger intermolecular forces → higher melting and boiling points
- 5. Surface Tension Surface tension is a measure of the toughness of the surface of a liquid Stronger intermolecular forces → higher surface tension.
- 6. Viscosity Viscosity is a measure of how well substances flow. Stronger intermolecular forces → higher viscosity.

Phase at room temperature When molecules have strong intermolecular forces of attraction, they are packed close together. They often exist as condensed phase (solid or liquid) at room temperature. When molecules have weak intermolecular forces of attraction, they are far apart from each other. They often exist as gas at room temperature.
- 8. Solubility Solubility refers to the ability of a substance to dissolve in a given amount of solvent at a specified temperature. Recall the rule “like dissolves like.” When the solute and the solvent both exhibit the same intermolecular forces of attraction, they form a solution.
- 9. Melting point and Boiling point If molecules stick together more, they'll be tougher to break apart Stronger intermolecular forces → higher melting and boiling points
- 10. Surface Tension Surface tension is a measure of the toughness of the surface of a liquid Stronger intermolecular forces → higher surface tension.
- 11. Viscosity Viscosity is a measure of how well substances flow. Stronger intermolecular forces → higher viscosity.
- 12. Vapor pressure This is a small amount of gas that is found above all liquids. Stronger intermolecular forces → Lower vapour pressure.
- 13. Activity: 1. List the following molecules in order of increasing surface tension: C3H8, CH4, CH3COOH, C2H6 2. List the following molecules in order of increasing boiling point: Br2, F2, I2, Cl2, 3. Which has the higher vapour pressure, C20H42 or C30H62?
- 14. LET’S ANSWER 1. List the following molecules in order of increasing surface tension: C3H8, CH4, CH3COOH, C2H6 Answer: Higher surface tension corresponds to stronger intermolecular forces. 1. CH3COOH has the ability to hydrogen-bond. It will probably have the strongest intermolecular forces. 2. CH3COOH is the only one of these molecules to have a dipole, and we already decided it has the strongest intermolecular forces.
- 15. 3. Of the molecules that are left, the largest one (C3H8) likely has the strongest London dispersion forces. The smallest (CH4) likely has the weakest intermolecular forces. The answer is: CH4, C2H6, C3H8, CH3COOH 2. List the following molecules in order of increasing boiling point: Br2, F2, I2, Cl2, Higher boiling points will correspond to stronger intermolecular forces.
- 16. 1. None of these have hydrogen bonding. 2.None of these have dipoles. 3. Bigger molecules will have stronger London dispersion forces. So I2 has the strongest forces, and F2 will have the weakest. Correspondingly, I2 will have the highest boiling point and F2 will have the lowest boiling point. Answer: F2, Cl2, Br2, I2
- 17. 3. Which has the higher vapour pressure, C20H42 or C30H62? Answer Higher vapour pressures correspond to weaker intermolecular forces. 1. None of these have hydrogen bonding.
- 18. 2. None of these have dipoles. 3. Bigger molecules will have stronger London dispersion forces. So, C30H62 has the stronger intermolecular forces and C20H42 has the weaker intermolecular forces. Answer: C20H42 has the higher vapour pressure, since the molecules stick together less
- 19. ASSIGNMENT: Explain how intermolecular forces affect the properties of the following substances. 1. Which has higher boiling point, H2O or H2S? 2.Which is most likely solid, F2 or I2?
