When temperature increases, so does pressure, and vice versa. This is called a directly proportional relationship.

When the temperature of a gas inside of a container is increased, the gas molecules increase the speed at which they travel, hitting the side of their container more, increasing the pressure.

• For this law to work, the volume must be constant.
• A change in volume would disrupt Gay-Lussac's Law.

REAL LIFE EXAMPLES

• Tire Pressure: the tires of your car deflate in the cold
• Ping Pong Balls: dip them in cold water to get rid of dents
• Footballs: having one outside on a cold day deflated them
