kinetic theory and gases Flashcards
1
Q
ideal gas
A
a gas that has internal energy only in the form of random kinetic energy
2
Q
assumptions of kinetic model of a gas
A
- the gas contains a large number of particles
- particles move rapidly and randomly
- all collisions are perfectly elastic
- negligible attractive forces between particles
- time for collisions to happen is negligible compared to time between collisions
- particles have a negligible volume compared with the volume of gas in the container.
3
Q
boyles law
A
the volume of a fixed of a fixed gas is inversely proportional to the pressure exerted on the gas
4
Q
Charles’ law
A
at a constant pressure the volume of a gas is directly proportional to its absolute temperature
5
Q
the pressure temperature law
A
at a constant volume the pressure of a gas is directly proportional to it’s absolute temperature
6
Q
the Boltzmann constant
A
it is a constant used when relating the temperature of the gas to the mean translational kinetic energy
