Explain with the help of kinetic theory, why pressure of a gas in its container walls rise when volume is reduced?

In the light of kinetic theory of gases, why pressure of container increases when the gas is heated?

Kinetic energy and pressure of a gas of unit volume are related as:

Give reason : a gas exerts pressure on the walls of the container.

Why liquids exert pressure on the walls of the containing vessel?

At 27^(@)C a sample of ammonia gas exerts a pressure of 5.3 atm. What is the pressure when the volume of the gas is reduced to one-tenth of the original value at the same temperature ?

A cylinder with a movable piston contains3moles of hydrogen atstandard temperature and pressure. The walls of the cylinder are made of a heat insulator, and the piston is insulated by having a pile of sand on it. By what factor does the pressure of the gas increase if the gas is compressed to half its original volume ?
