Solution
Based on the change in temperature two types of changes take place in a substance
- Endothermic change 2) Exothermic change
- Those changes in which a substance gets energy in the form of heat from its surroundings and changes into different substances are called endothermic changes.
- For example vaporization of water, in this case, water absorbs heat energy from the surroundings and forms water vapor.
- So the vaporization of water is an endothermic change.
