When energy is added to a liquid, its particles begin to move (kinetic energy increases). If sufficient energy is the particles will completely the intermolecular forces, which causes them to move from each other. When this happens, the liquid ; When energy is removed from a gas, the particles begging to; Since the particles are moving the pull of intermolecular forces on them gets If sufficient energy is the intermolecular forces can pull them together, allowing them to only move each other. Then, the gas: 620 DAA O Type here to search
