- Burning of LPG involves both physical and chemical changes because when LPG comes out of cylinder and is converted from liquid to gaseous state it is a physical change.
- When the gas burns in air it is a chemical change.
- Similarly ,burning of candle is a physical as well as a chemical change because solid wax changes to liquid form and its form can be regained hence it is a physical change but burning of wax is a chemical change.
