How is pressure affected by the collision of gas particles?

Answer 1

Raising the temperature of a gas raises the Average Molecular Kinetic Energy of the gas......which causes the velocity of the gas molecules to rise......which causes MORE COLLISIONS of the gas particles with each other and with the walls of the container ......which causes an INCREASE IN PRESSURE.

Decreasing temperature causes the opposite.


If the VOLUME of the container is DECREASED, it causes an INCREASE IN COLLISIONS with each other and with the walls of the container ......which causes an INCREASE IN PRESSURE.

Increasing the volume causes the opposite.

Answer 2

The pressure of an ideal gas IS the collision of gas molecules.
