In a desert plant, the evaporation of a small amount of water provides a significant cooling effect. Which mechanism allows this efficient heat removal?
Q1. In a desert plant, the evaporation of a small amount of water provides a significant cooling effect. Which mechanism allows this efficient heat removal?
Answer: Breaking of hydrogen bonds
Explanation: The high heat of vaporization is due to the energy required to break hydrogen bonds between water molecules. Covalent bonds remain intact.
