Q1. A student running in the sun begins to sweat to lower their body temperature. Which property of water allows for this effective cooling?
Answer: High heat of vaporization
Explanation: Evaporative cooling relies on high heat of vaporization; specific heat is tempting but it refers to temperature stability, not cooling via phase change.
