This document discusses the kinetic theory model of gases and the relationships between temperature, pressure, and volume of gases. It explains that:
1) According to kinetic theory, gases are composed of particles that move randomly in all directions and collide with each other and the container walls, exerting pressure.
2) Boyle's law states that for a fixed mass of gas at constant temperature, pressure and volume are inversely proportional.
3) Charles' law states that for a fixed mass of gas at constant pressure, volume is directly proportional to absolute temperature.
4) Gases need to be stored at higher pressures in small volumes because they take up large volumes at atmospheric pressure.

8). kinetic theory of gas (finished)
This document discusses the kinetic theory of gases and its assumptions. It introduces the concepts of pressure, temperature, volume, and kinetic energy at the microscopic and macroscopic levels. The relationships between these quantities are derived based on the assumptions of ideal gases. Specifically, the pressure of an ideal gas is shown to be proportional to the average kinetic energy of its molecules. The equipartition theorem is also discussed, relating the kinetic energy and degrees of freedom of gas molecules to temperature. Expressions are derived for specific heat capacity and the ideal gas law. The differences between real and ideal gases are explained using van der Waals equations.
Vander waals equation
This document discusses key concepts in thermodynamics including:
1. Degree of freedom is defined as the number of possible independent ways a system can have energy.
2. Equipartition theorem states that each degree of freedom contributes 1/2kT to the internal energy of a molecule.
3. The internal energy of an ideal gas can be written as a function of the number of moles, degrees of freedom, and temperature.
4. Real gases are better modeled by the van der Waals equation of state, which accounts for molecular size and attractive forces between molecules.
Thermal diffusuvity & newtons law of cooling
Thermal diffusivity is a physical property that measures how quickly a material responds to changes in thermal energy. It is the ratio of a material's ability to conduct heat to its ability to store heat. Materials with higher thermal diffusivity respond faster to temperature changes. Thermal diffusivity can be measured directly using methods like the flash method or indirectly using temperature history charts. Newton's Law of Cooling states that the rate of heat loss from a body is proportional to the difference between the body's temperature and the temperature of its surroundings. This law can be used to model and predict how quickly hot water in pipes will cool over time.
Intro to gases and gas laws
The document discusses the kinetic molecular theory of gases and the gas laws. It explains that according to the kinetic molecular theory, gas particles are in constant, random, straight-line motion and have no intermolecular forces. The gas laws - Boyle's law, Charles' law, and Gay-Lussac's law - describe the relationships between pressure, volume, temperature for an ideal gas. Boyle's law states that pressure and volume are inversely proportional at constant temperature. Charles' law states that volume and temperature are directly proportional at constant pressure. Gay-Lussac's law states that pressure and temperature are directly proportional at constant volume. Examples are given to demonstrate using the gas laws to calculate unknown properties.
01 part1-ideal-gas
This document discusses ideal gases and their properties. It defines an ideal gas as a theoretical gas composed of point-like particles that obey gas laws perfectly. Some key properties of ideal gases are that they have negligible volume and mass and undergo perfectly elastic collisions. The document also covers gas laws such as Boyle's, Charles', and Gay-Lussac's laws. It provides the ideal gas equation of state and defines terms like molar mass, gas constant, pressure units and heat capacities. Several example problems applying the ideal gas law are also included.
Gay Lussac’s Law
Gay-Lussac's law states that the pressure of a fixed mass of gas is directly proportional to its temperature when volume is held constant. The document provides an example of using this law to calculate the new pressure of oxygen in a container if the temperature is increased from 40°C to 100°C, given the original pressure is 21.5 atmospheres. It outlines the steps of first converting temperatures to Kelvin and then multiplying the original pressure by the ratio of the new and original Kelvin temperatures to determine the increased pressure.

BIO-VISION'S MULTIMEDIA CLASS - Charles law
Charles' Law states that the volume of a gas is directly proportional to its temperature when pressure is kept constant. Specifically, if the temperature of a gas doubles, its volume will also double as long as pressure remains unchanged. This relationship can be expressed as V1/T1 = V2/T2, where V is volume, T is temperature, and the subscripts 1 and 2 refer to two different temperatures.

Pressure in gases
The document discusses the relationships between pressure, temperature, and volume in gases. It explains that gas pressure increases with temperature because the faster moving gas molecules collide with the container walls more frequently and forcefully. It also explains that gas volume increases with temperature as the molecules move further apart while maintaining a constant pressure through less frequent but more forceful collisions. Finally, it notes that gas pressure increases with decreasing volume, as molecules collide with the walls more often in a smaller space.
States of matter - Gaseous state
There are five states of matter: solid, liquid, gas, plasma, and Bose-Einstein condensate (BEC). Plasma is common among stars but not on Earth, while BEC only forms at extremely low temperatures near absolute zero when atoms lose kinetic energy and clump together. Gases are characterized by diffusion, the movement from high to low concentration, and effusion, movement through a small pore. Several gas laws describe gas behavior, including Boyle's law relating pressure and volume, Charles' law relating volume and temperature, Avogadro's law of equal volumes containing equal molecules, and Dalton's law of partial pressures. Real gases deviate from the ideal gas model due to intermolecular forces
Modes of energy transfer in soil
1. Three main modes of energy transfer in soil are conduction, convection, and radiation. Conduction involves direct particle contact, convection involves bulk fluid movement, and radiation does not require matter.
2. The surface energy balance equation states that energy in equals energy out at the soil surface. This includes net radiation, heat flux into soil, sensible heat flux to air, and latent heat from evaporation.
3. Thermal conductivity describes a material's ability to conduct heat and is measured in watts per meter-kelvin. It is dependent on soil composition, texture, water content, and compaction. Thermal diffusivity incorporates conductivity and describes the speed of heat propagation.

Measurement system
- 2. WHAT IS MEASUREMENT • MEASUREMENT IS THE PROCESS OF COMPARING A GIVEN QUANTITY OF THINGS TO THAT OF PRE DEFINED QUANTITY. • EXAMPLE: MEASURING A LINE WITH RULER,WEIGHING VEGETABLES WITH IRON BLOCKS(1 KG,2 KG,5 KG), WEIGHING SCALE. RULER WEIGHING MACHINE
- 3. NEED OF MEASUREMENT SYSTEM • MEASUREMENTS ARE THERE TO PROVIDE MEANS FOR EITHER COMPARING 2 OR MORE ENTITIES (MAY BE PHYSICAL OR LOGICAL). • EXAMPLE: SOMETHING IS GREATER/SMALLER/BRIGHTER/FARTHER/ HEAVIER/LIGHTER/FASTER THAN SOMETHING BUT BY WHAT AMOUNT. THERE MUST BE SOME STANDARD SCALE FOR ALL THESE ENTITIES. • SECONDLY TO INDICATE THE EXACT QUANTITY OF ANY ENTITY. • EXAMPLE: MOON IS AT VERY LARGER DISTANCE FROM EARTH BUT EXACTLY HOW MUCH. I NEED TO BUY SOME QUANTITY OF FOOD, WHEAT AND GRAINS FROM SHOP KEEPER, BUT AGAIN WHAT QUANTITY.. (ESPECIALLY WHILE YOU ARE ORDERING THROUGH TELEPHONE… IMAGINE WHAT WILL HAPPEN IF YOU DON’T HAVE MEASUREMENTS LIKE GRAM, MILI-GRAM, KILOGRAM, POUNDS… ETC).
- 4. TYPES OF MEASUREMENT SYSTEM THERE ARE VARIOUS TYPES OF MEASUREMENT SYSTEMS: 1. FPS UNIT SYSTEM( FOOT,POUND,SECOND) USED IN BRITAIN BEFORE INTRODUCTION OF SI UNITS. 2. MKS SYSTEM (METER, KILOGRAM ,SECONDS) USED IN FRANCE 3. CGS SYSTEM(CENTIMETER,GRAM SECONDS) USED IN FRANCE 4. SI SYSTEM (SYSTEM INTERNATIONAL) MODIFIED FORM OF MKS UNITS, USED TODAY
- 5. S.I SYSTEM OF UNITS QUANTITY UNITS LENGTH m(METRE) WEIGHT kg(KILOGRAM) TIME s(SECONDS) TEMPERATURE K(KELVIN) AMOUNT OF SUBSTANCE mole(MOLES) ELECTRIC CURRENT A(AMPERE) INTENSITY OF RADIATION cd(CANDELA) ANGLE rd(RADIAN)
- 6. APPLICATIONS THERMOMETER: 1. A THERMOMETER IS A DEVICE THAT MEASURES TEMPERATURE GRAIDENT(DIFFERENCE). 2. IT HAS TWO IMPORTANT PARTS: i. BULB ii. SCALE INDICATOR
- 7. APPLICATIONS RAIN GAUGE 1. A RAIN GAUGE IS AN INSTRUMENT USED BY METEOROLOGISTS AND HYDROLOGISTS TO MEASURE PRECIPITATION (E.G. RAIN, SNOW, HAIL OR SLEET) IN A CERTAIN AMOUNT OF TIME. IT IS USUALLY MEASURED IN MILLIMETRES.
