Particle motion in gases Flashcards
1
Q
Average energy in kinetic stores is related to…
A
Temperature.
2
Q
What happens as gas particles move around at high speeds?
A
They bang in to each other and anything else that gets in the way. When they collide with something, they exert a force/pressure on it.
3
Q
A change in pressure can cause…
A
A change in volume.
4
Q
The pressure and the volume are…
A
Inversely proportional-at a constant temperature, when volume goes UP pressure goes DOWN (And when volume DECREASES, pressure INCREASES.)
5
Q
For a gas of fixed mass at a constant temperature the relationship is…
A
pV= Constant
Pressure x volume = constant temperature.
6
Q
Doing work on a gas can increase its…
A
INTERNAL energy which can increase it’s TEMPERATURE.
