When molecules are the size of balls, phase changes such as melting and evaporation can be very “moving” events! A tubful of rubber balls is a perfect demonstration device for comparing the energy and motion of molecules in the solid, liquid, and gas phases. It’s time to put the “kinetic” back into the kinetic–molecular theory!
