Answer

burning of candle

Reason — When a candle is lighted it produces carbon dioxide and water vapours as the new substances and along with it there is evolution of heat and light. The candle also becomes smaller and smaller. This shows a chemical change. When a candle burns wax melts and turns into liquid state that falls on floor and again it solidifies which shows a physical change.
