What is an exothermic change? and what is an endothermic change? Give examples.
- Exothermic changes are those changes that release heat, for example, during respiration the glucose molecules breakdown to produce energy, which we can utilize for our day to day actions.
- Endothermic changes are those changes that involve absorption of heat, for example, during vaporization of water. molecules of liquid water absorb latent heat and gets converted into water vapors.
