6.3.3.1 Particle Motion in Gases Flashcards
1
Q
What are molecules of gas regular motion?
A
- constant random motion
2
Q
What is the temperature of gas related to?
A
- average kinetic energy of molecules
3
Q
What happens when you change the temperature of a gas at a constant volume (known as Pressure law)
A
- changes the pressure exerted by the gas
4
Q
What happens at a higher temperature?
A
- the greater the average kinetic energy
- so faster the average speed of the molecules
5
Q
What happens when molecules collide with the wall of their container?
A
- exert a force on the wall
6
Q
What is gas pressure?
A
- total force exerted by all molecules inside container on a unit area of the walls
