Question

How is pressure developed in a container full of gas

Answer 1

Gaseous molecules are free to move in the container.The molecules collide with each other and with the wall of the container.On the wall the molecules exert force.The force per unit area is called the pressure of the gas.

Answer 2

Pressure, is developed by the gasmolecules hitting the sides of the container walls. ... to develop a huge pressure in the container you can try to put in more gas, so that more molecules can exert a greater force on the wall for that same area (increase n), increasing the temperature (T) or reduce the volume (V)
