Gas Temperature Flashcards
1
Q
What do gases exert on the walls of a container?
A
Very small forces
2
Q
What happens if you add more air particles to a container that cannot expand?
A
The pressure increases
3
Q
What happens when the temperature of a gas increases?
A
The gas particles have a higher average speed and the particles collide more frequently with the sides of the container and so the collisions produce a bigger force over a certain area. The pressure increases.
4
Q
What can you use to measure pressure in a container?
A
Pressure gauge
5
Q
What unit is pressure measured in?
A
Pascals (Pa)
