Charles's Law: Temperature and Volume
Charles's Law states that at constant pressure, the volume of a gas is directly proportional to its Kelvin temperature.
3
Charles's Law cont.
The straight line for the gas indicates that volume and temperature are in direct proportion.
4
Charles's Law cont.
When temperature increases, volume increases, and when temperature decreases, volume decreases.
5
Multiple Choice
According to Charles's Law when the temperature decreases the volume will
decrease
increase
stay the same
6
Multiple Choice
According to Charles's Law, when the temperature increases, the volume will
increase
decrease
stay the same

Kinetic Explanation of Charles's Law
As the gas particles are heated, they move faster and have more collisions with the sides of the container and move the piston upward creating an increase in volume.
8
Charles's Law cont.
The equation to the right can be used to find the volume of temperature.
Must Convert to Kelvin.
