A gas is put into a cosed container. The container and the gas inside it are heated.
What will happen to the pressure inside the container?

When gases in containers are heated, their molecules increase in average speed. This means that they exert a greater force when they collide with the container walls, and also collide with the walls more frequently. The gas is therefore under greater pressure when its temperature is higher.
