AM+CHARLE'S+LAW

Charle's Law- states that for a fixed amount of gas at a constant pressure, the volume of the gas increases as the temperature of gas increases and the volume of the gas decreases as the temperature of the gas decreases.

The formula for the law is:

Example: A sample of neon gas occupies a volume of 800mL at 25ºC. What volume will the gas occupy at 50ºC if the pressure remains constant?

V1 of Ne = 550mL ; T1 of Ne = 298K ; T2 of Ne = 323K Looking For: V2 of Ne in mL

Rearange Charles' law to obtain the new volume, V2.

Substitute all given values into the equation: V2 = (800mL Ne)(323K) / 298K = 815mL Ne
 * The volume of the gas increases as the temperature increases.**
