1. Introduction to Kinetic Theory:
- Kinetic Theory of Gases is based on the idea that gases consist of a large number of small particles (atoms or molecules) that are in constant, random motion.
2. Assumptions of Kinetic Theory:
- Particles in a gas are considered point masses with negligible volume.
- Collisions between particles are perfectly elastic, meaning there is no loss of energy during collisions.
- The forces of attraction or repulsion between particles are negligible except during collisions.
3. Pressure and Kinetic Theory:
- The pressure exerted by a gas is a result of the numerous collisions between its particles and the walls of the container.
- The kinetic theory relates pressure to the average kinetic energy of the gas particles.
4. Derivation of Gas Laws:
- Kinetic Theory helps derive macroscopic gas laws such as Boyle’s Law, Charles’ Law, and Avogadro’s Law from microscopic principles.
5. Mean Free Path:
- The average distance a particle travels between collisions is called the mean free path. It is inversely proportional to the density of the gas.
6. Root Mean Square (RMS) Speed:
- The RMS speed is the square root of the average of the squares of the speeds of individual gas particles. It is related to temperature.
7. Distribution of Molecular Speeds:
- Maxwell-Boltzmann distribution describes the distribution of speeds of particles in a gas at a particular temperature.
8. Kinetic Energy and Temperature:
- Kinetic energy is directly proportional to the temperature of the gas. The higher the temperature, the greater the average kinetic energy of the gas particles.
9. Specific Heat Capacities:
