Answer: A) number of collisions with the container wall increases.
Explanation: Pressure is defined as the force acting per unit area.
It is caused due to bombardment of gas molecules on the walls of the container.
Kinetic molecular theory states that:
1. Gases consist of large number of small particles.
2. Collision between gas particles and between particles and container walls are elastic collisions
.
3. Gas particles are in continuous motion.
4.
There are no forces of attraction between gas particles
.
5. The temperature of a gas depends on the average kinetic energy of the particles of the gas.
