Study Notes
Kinetic Theory of Gases
- In the basic version of the kinetic theory model, there are no interactions between gas particles, meaning they neither attract nor repel each other.
- Gas particles undergo elastic collisions, which means they bounce off each other without losing energy.
- According to the kinetic theory, gas particles are described as tiny, hard spheres that are in constant random motion.
- The temperature of an ideal gas is directly proportional to the average kinetic energy of its particles.
- The size of helium atoms is relative to their spacing when the gas is at low pressure and low temperature.
- The fundamental idea about the behavior of gases in the kinetic theory is that they consist of tiny particles in constant motion.
- The actual volume of gas molecules is assumed to be negligible compared to the volume of the container.
- Gas molecules move in random, straight-line paths, changing direction only when they collide with the container or other gas molecules.
- The assumption about the interactions between gas molecules is that they are negligible, except during collisions.
- The pressure exerted by a gas is caused by the collisions of gas molecules with the container walls.
