All about Pressure and Gases
Gases spread out to fill any container they are in and push against its walls. This push is called pressure. Gas pressure changes when a gas is heated, cooled or squeezed into a smaller space.
Car tyres are filled with air at a set pressure so they grip the road well and carry the weight of the car safely.
