As the molecules heat up and move faster, they move apart. Thus, air, like most other substances, expands when heated and contracts when cooled. Because there is more space between molecules, the air is less dense than surrounding matter, and hot air floats upward. As the air cools, after pumping through the pump, the air contracts causing the air mattress to feel like it is deflating and if the user applies more air to the bed, the pressure will become more stable over time.
