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 (hit) 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

Gas has a less intermolecular force of attraction due to which they move freely in the container and then collide with each other and with the wall of the container. Due to this collision the force is exerted and the pressure is developed.
