Pressure is merely force per area, so if the force increases but the box stays the same size, the pressure has increased. Air density can decrease with temperature if pressure is also decreasing. If pressure is constant, this cannot happen (they would be inversely related). Any time you specify a relation between any two of pressure, density or temperature you must hold the third constant or specify its behavior.
air pressure: Air has weight. Air pressure is the weight of the air, or atmosphere, pushing down on Earth. The closer you are to sea level, the higher the air pressure because thereâs that much air above you. The higher you are, there is less air pressure.
