What is an Ideal Gas? The Kinetic Model of an Ideal Gas - IB Physics
This lecture states the Kinetic Model of an Ideal Gas, which is just a definition of what an ideal gas is using the concept of kinetic energy: in an ideal gas, all internal energy added to the gas becomes random kinetic energy in the particles of the gas, and therefore increases the temperature. I use several examples to explain why we use this definition for an ideal gas and the list of requirements and assumptions for a gas to only gain kinetic energy when internal energy is added. Those requirements are:
-The gas is made up of a very large number of small identical molecules in random motion.
-There can be no intermolecular forces or bonds between the particles.
-All collisions between particles, and between particles and the barrier, must be perfectly elastic.
-There are just as many molecules moving in one direction as any other direction (the gas as a whole doesn’t travel in any one direction).
-The individual forces from collisions between molecules average out to a uniform pressure throughout the gas.
