A gas in a cylinder is compressed quickly by a moving piston. The temperature of the gas increases.
Which statement explains this in terms of the gas particles?
Particles are pushed closer, so they collide with each other more
Particles hit the walls more often, so the walls heat the gas
Particles lose potential energy as they are squeezed together
Particles bounce off the moving piston at a higher speed
