उत्तर
Chemical changes:
Since heat is a form of energy it plays a major role in chemical changes. In some cases, chemical reactions need heat to begin, and also heat determines the speed at which reactions occur. When we cook food, we light the wood and it catches fire and the food particles become soft because of the heat energy. These are all the chemical changes taking place due to heat.
