Gas pressure and the kinetic theory
Reducing the volume of the gas
Increasing the temperature of the gas
What happens to the speed of the molecules?
No change
The speed does not change. Only heat can increase the speed of the molecules.

What happens to the number of collision every second

Because the molecuels have less distance to travel so they collide more often with the walls.

Because the average speed of the molecules increaes therefore they hit the wall more often.
What happens to the pressure of the gas.

If the collisions per second increase then so will the pressure.
