Properties of Gases:. Gases have an indefinite shape..

Gas pressure is the result of constantly moving molecules striking the inside surface of its container..

Atmospheric pressure:. Result of air molecules striking various surfaces in the environment..

In a gaseous system, there are three ways to change the pressure..

Boyle’s Law:. The volume of a gas is inversely proportional to the pressure when the temperature remains constant..
