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 »

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

The furnace pressure switch shuts down the furnace if the unit has improper air pressure caused by venting issues. Potential causes of pressure change that signal a problem include leaks, restrictions in the intake air v... More »

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 »

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 »

Liquids consists of particles that are close together with no set arrangement, can flow easily, can take on the shape of any container it occupies and cannot be compressed easily. There are three main states of matter: s... 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 »
