D.liquid to gas\nwhen the molecules move with increased speed, their average kinetic energy increases, causing the intermolucular forces to weaken and so they move further away from each other and eventually change phase. this is exactly what happens when you heat something, the molecules, gain energy, vibrate about theuir mean positions, at thresh-hold amplitudes or velocities, they break the molecular forces and chenge phase from solid to liquid or liquid to gas
