Pressure is the force that is exerted within a given volume of space.

###### Understanding Pressure

Concept #1: Pressure Units

Pressure represents the force that a gas molecule exerts against the walls of its container. It can be depicted as force per area. Example #1: What happens to the pressure if the same amount of gas molecules is transferred from a 5.0 L containerto a 10.0 L container?

Concept #2: Pressure Unit Conversions

Example #2: The pressure in Denver, Colorado (elevation 5280 ft), averages about 24.9 inHg. Convert this pressure intommHg and atm.
