Why does decreasing the volume of gas cause the pressure to increase if temperature is constant
Yuri [45]

There's less space, causing the air particles to collide with the walls of the container more frequently. Pressure is that energy caused by molecules striking a surface. Thus, compacting air molecules leads to higher pressure.
