Effect of pressure
The pressure of a gas is due to the particles colliding with the walls of the container that the gas is held in
If gases are compressed into a smaller volume, there will be more particles hitting the container wall every second
The more frequent the collisions with the container wall the higher the pressure
Effect of temperature
Increasing the temperature makes particles move faster and increases the frequency of collisions with the container walls
Therefore, increasing the temperature increases the pressure if the volume stays constant
