Why is burning of a candle an example of both a physical and a chemical change ?
Answer
When a candle is lighted it produces carbon dioxide and water vapour as the new substances and along with it there is evolution of heat and light. This shows a chemical change. When a candle burns wax melts that falls on floor and again it solidifies which shows a physical change. So, burning of a candle is both a physical and a chemical change.
