Unlike chemical change, wherein enormous energy is absorbed or given out as heat, light or sound energy Example of both changes occuring simultaneously Burning of candle: While melting of wax is a physical change, as the state of the substance changes from solid to liquid, burning of wax is a chemical change, as after consuming energy from wax, light lits up. In the cylinder it exist as a liquid.
