Explain how heat bring about chemical change in a matter? Explain giving example.
The changes in which new substances are formed are called chemical changes. The properties of new substances formed in chemical changes are entirely different from those of the original substances.
During a chemical change, a substance undergoes a change in its chemical composition. For example, the burning of a candle is one example of a chemical change. When we light the candle, then the wax present in it starts burning to produce heat and light. The burning of wax also produces carbon dioxide gas, water vapor, and soot. We cannot combine all the products of burning wax to get back the original candle. Hence, the burning of candle wax is an example of chemical change.
