The particles of gas are far apart. They have very little force of attraction between then. Thus, they have the highest kinetic energy. Due to this, the particles move with a great speed, hitting the walls of the container.Thus a gas exerts pressure on the walls of the container.

Its easy ! As we know , particles of matter are continuous in nature and particles of gas have a lot of space and negligible force of attraction (cohesion) between them. Therefore, they move the fastest and thus collide with the walls of the container exerting a pressure on the walls of the container.

Due to high kinetic energy possessed by the gas particles, they randomly move at a high speed within the container.
Due to this random movement, the particles hit each other as well as the walls of the container. The force by which these particles strike the container exerts a pressure on its walls

The molecules are continually colliding with each other and with the walls of thecontainer. When a molecule collides with the wall, they exert small force on the wall The pressure exerted by the gas is due to the sum of all these collision forces.The more particles that hit the walls, the higher the pressure.
