New cards

How would you describe particles in a gas?

Constantly changing direction & at different speeds

2
New cards

What happens when you increase the temperature of gas particles?

  • + KE

  • + speed

  • + collisions with other particles and container surface

3
New cards

When the gas particles collide with the surface of a sealed container…

They exert a force at right angles to the container surface.

4
New cards

Increased net force on container surface =

Increased pressure

5
New cards

What should you always talk about when given a question on gas pressure?

NET FORCE

6
New cards

When the container size is decreased, does the pressure increase or decrease?

Increase

7
New cards

Why does gas pressure increase when making the container smaller?

  • more frequent collisions due to smaller volume ( with eachother and surface)

  • Higher net force exerted (at right angles to the surface)

  • Thus higher pressure
