The wax on a candle turns from a solid to liquid once the candle is lit. What happens first fo cause this solid to liquid phase change?

• Heat from the flame increases the potential energy of the wax molecules

• Heat from the flame increases the kinetic energy of the wax molecules

• Heat from the flame breaks the bonds in the wax molecules

• Heat from the flame fuses the wax atoms into molecules
