What does the constant bombardment of gas molecules against the inside walls of a container produce?

The constant bombardment of gas molecules against the inside walls of a container produces Pressure.

Explanation:
                    Pressure is defined as Force per unit Area.

                                        P  =  F  /  A

In case of gases, the gas molecules have high Kinetic Energy and they move with high velocity. This cause them to strike against the inside wall of the container. Pressure is directly proportional to temperature. Increase in temperature cause to increase the Kinetic Energy of molecules, Hence, the rate of collisions increases resulting in increasing the pressure.
