According to Elmhurst College, gas exerts pressure due to the force gas exerts on a container's walls. An example is a person blowing up a balloon. The walls of the balloon expand due to the pressure of the air molecules... More »

Gases can be compressed because each gas particle has relatively vast amounts of room between it and all other gas particles the majority of the time. Thus, compression, which is essentially forcing the gas particles clo... More »

Air exerts pressure because its molecules are in constant motion; they impact against objects they encounter and exert a pushing force against them. The force of multiple impacts over an area is air pressure. More air mo... More »

According the kinetic molecular theory, gas in a closed container exerts pressure on the walls of that container because its molecules are in constant motion, which causes some molecules to impact the walls. The more the... More »

A gas will exert pressure on its container by continuously trying to expand its area, which pushes gas molecules against the container's walls. A gas with higher energy will exert more pressure than one with lower energy... More » Science Physics Motion & Mechanics

In a given container, billions of particles of gas are constantly moving around randomly, colliding with the sides of the container. With thousands of collisions per second, individual collisions do not register, but an ... More »

Newton's second law of motion states that the force that an object exerts is equal to that object's mass times its acceleration. The amount of force that individuals can exert is directly proportional to their mass and t... More »
