Kinetic Theory of Gases and Radiation
Overview
- Weightage of the chapter: 7 marks with options, 5 marks without options
- Topics covered: Introduction, behaviour of a gas, ideal gas and real gas, mean free path, pressure of ideal gas, root mean square (rms) speed, interpretation of temperature, law of equipartition of energy, specific heat capacity, absorption, reflection, and transmission of heat radiation, perfect blackbody, emission of heat radiation, Kirchhoff's law, and Stefan-Boltzmann law of radiation
Introduction to Gases
- Gas laws include Boyle's law, which states that for a fixed mass of gas at constant temperature, pressure is inversely proportional
- Pressure of a gas is related to its volume, temperature, and molecular motion
Behaviour of a Gas
- Gases exhibit certain characteristics that can be described by the kinetic theory of gases
Ideal Gas and Real Gas
- Ideal gas: a hypothetical gas that obeys the ideal gas equation, PV = nRT
- Real gas: a gas that does not obey the ideal gas equation, due to intermolecular forces and molecular size
Mean Free Path and Pressure of Ideal Gas
- Mean free path: the average distance traveled by a gas molecule between collisions
- Pressure of ideal gas: the force exerted by the gas molecules on the walls of the container, described by the ideal gas equation
Root Mean Square (RMS) Speed and Temperature
- RMS speed: the square root of the average of the squared speeds of the gas molecules
- Temperature: a measure of the average kinetic energy of the gas molecules
Law of Equipartition of Energy
- The law states that the total energy of a system is equally distributed among the degrees of freedom of the system
Specific Heat Capacity
- The amount of heat energy required to change the temperature of a unit mass of a substance by a unit temperature
Radiation and Heat Transfer
- Heat radiation: the transfer of energy through electromagnetic waves
- Absorption, reflection, and transmission of heat radiation occur at the surface of a body
- Perfect blackbody: a body that absorbs all incident radiation, with no reflection or transmission
- Emission of heat radiation: the process by which a body loses energy through radiation
- Kirchhoff's law of heat radiation: relates the emissivity and absorptivity of a body
- Stefan-Boltzmann law of radiation: describes the total energy radiated by a blackbody per unit surface area
