What happens to the gas pressure in a sealed gallon can when heated?

Answer 1

A good example of this would be a hot air baloon. When you heat the air (gas) inside, the molecules spred out, move faster and overall the whole quantity gets less dense, and moves up through the cooler air outside.

Answer 2

When a sealed gallon can is heated, the temperature of the gas inside the can increases, causing the gas molecules to move faster and collide more frequently with the walls of the can. This increase in collisions results in an increase in the gas pressure inside the can.

Answer 3

Gas expands under heat so the pressure would rise when a sealed gallon can is heated.

Answer 4

The gas pressure within a sealed can will decrease when it is cooled.
