Ncert class 10 - science - chapter 3 - metals and non-metalsEswariKumaravel
The document discusses the properties of metals and non-metals. It describes how metals are lustrous, malleable, ductile, and good conductors of heat and electricity, while non-metals lack these properties. Experiments are presented to demonstrate that metals are lustrous, hard except for a few, malleable by hammering into thin sheets, and ductile by pulling into wires. Other experiments show that metals conduct heat by melting wax and conduct electricity by lighting a bulb. The document contrasts how metals and non-metals react with oxygen, water, acids, and how metals react in salt solutions in displacement reactions.
This document discusses combustion and flames. It defines combustion as a chemical process where a substance reacts with oxygen to produce heat. Three conditions are needed for combustion: a fuel, oxygen, and heat. It describes the structure of a candle flame as having three zones - an outer blue zone of complete combustion, a middle yellow luminous zone of partial combustion, and an inner black zone of unburned fuel vapors. It also discusses different types of fuels and their calorific values, as well as the harmful environmental effects of burning fuels like air pollution and global warming.
This document provides an overview of matter and its different states. It discusses that matter is made up of particles that are continuously moving, have space between them, and attract each other. The three main states of matter are solids, liquids, and gases, which are determined by the characteristics of the particles. Changes in temperature and pressure can cause matter to change states through processes like melting, boiling, sublimation, and deposition. Evaporation is also explained as the process where liquid particles at the surface gain energy and change to vapor without reaching the boiling point. In summary, the document covers the basic physical properties and behavior of different forms of matter.
Chapter 1 some basic concepts of chemistry class 11 UPDATED PPTritik
The document summarizes several important concepts and laws in chemistry:
1) The law of conservation of mass states that matter is neither created nor destroyed in chemical reactions.
2) The law of definite proportions states that a chemical compound always contains the same elements in the same proportions by mass.
3) Gay-Lussac's law of gaseous volumes describes how gases combine or are produced in simple volume ratios in chemical reactions at the same temperature and pressure.
4) Avogadro's law states that equal volumes of gases under the same conditions contain an equal number of molecules.
Carbon is found in many forms including diamond, graphite and fullerenes. It forms the basis of all known life and is present in many fuels. Carbon has 4 valence electrons and forms covalent bonds by sharing electrons with other atoms. This allows carbon to form chains, branches and rings, resulting in over 3 million known carbon compounds. Key properties of carbon include catenation, isomerism, and the ability to form various functional groups that determine a compound's properties. Important carbon compounds include ethanol, ethanoic acid and soaps.

The document discusses concepts related to gravitation including Newton's universal law of gravitation, Kepler's laws of planetary motion, acceleration due to gravity, and equations of vertical motion. Some key points covered include:
1) Newton's universal law of gravitation states that the gravitational force between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
2) Kepler's laws describe the motion of planets and include that planets move in elliptical orbits with the sun at one focus.
3) Acceleration due to gravity on Earth is approximately 9.8 m/s2 and causes objects to experience weight. Weight depends on both mass and location.
Carbon is a versatile element that forms millions of compounds. It exists in many forms including diamond and graphite. Carbon is present in all living organisms and is the main component of fuels like coal.
Carbon atoms bond with other atoms through covalent bonds by sharing electrons. This allows carbon to form chains, branches and closed rings. Hydrocarbons contain only carbon and hydrogen and can be saturated or unsaturated. Functional groups determine the properties of carbon compounds.
Some important carbon compounds are ethanol, ethanoic acid, and soaps. Ethanol is used in drinks and medicines while ethanoic acid gives vinegar its sour taste. Soaps clean through micelle formation while detergents work better in
The document discusses the growth of nationalism in India and the non-cooperation movement led by Gandhi. It summarizes that British rule led to increased taxes, inflation, and famines during WWI, fueling Indian nationalism. Gandhi introduced satyagraha (non-violent resistance) and organized movements against oppressive British policies. The non-cooperation movement involved boycotts of British institutions and goods. It had widespread participation and effects but was called off after the Chauri Chaura incident of violence.
The document discusses control and coordination in living organisms. It describes how stimuli are received by receptors and responses are carried out by effectors. In animals, the nervous system and endocrine system work together to coordinate responses. The nervous system consists of neurons that transmit electrochemical signals through sensory, motor and interneurons. The human nervous system contains the central nervous system (brain and spinal cord) and peripheral nervous system. Reflex actions provide involuntary, rapid responses via a reflex arc. In plants, coordination occurs through plant hormones such as auxins and gibberellins, which influence growth and movements like tropisms in response to stimuli. The endocrine system also facilitates coordination in animals via glands like the adrenals, thyroid and pituitary
Chemistry(class11)-CLASSIFICATION OF ELEMENTS AND PERIODICITY IN PROPERTIESPawan Kumar
The document discusses the history and development of the periodic table. It explains that:
1) Elements have been organized into the periodic table based on their atomic weights and properties in order to systematically study and predict chemical behavior.
2) Early periodic tables were proposed by scientists like Dobereiner, Newlands, and Mendeleev based on trends in atomic weights, though Mendeleev's 1869 table was the most successful in predicting new elements.
3) Modern periodic tables are arranged by atomic number according to the periodic law proposed by Moseley, with elements grouped into blocks based on their electron configurations. The table better explains trends in physical and chemical properties.
1) The document discusses the classification of living organisms into a hierarchy of kingdoms, phyla/divisions, classes, orders, families, genera, and species based on their characteristics and evolutionary relationships.
2) There are five main kingdoms - Monera, Protista, Fungi, Plantae, and Animalia. Plants and animals are further divided into smaller subgroups.
3) Classification helps organize the vast diversity of life forms into manageable groups for study. Scientific naming using binomial nomenclature allows organisms to be uniquely identified.
1. Gravitation is the force of attraction between two objects due to their masses. The universal law of gravitation states that the gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
2. When an object falls towards the earth due to gravitational attraction, it is undergoing free fall. The acceleration during free fall is called acceleration due to gravity (g), which is about 9.8 m/s^2 on earth.
3. Archimedes' principle states that when an object is immersed in a fluid, it experiences an upward buoyant force equal to the weight of the fluid displaced by the object. This determines whether

The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptxMAGOTI ERNEST
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).
Authoring a personal GPT for your research and practice: How we created the Q...Leonel Morgado
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.
