Q1. A person sweats profusely during exercise to maintain a stable internal temperature. Which property of water is primarily responsible for this cooling effect?
Answer: High heat of vaporization
Explanation: Water's high heat of vaporization (574 Kcal/kg) allows efficient cooling. Specific heat is tempting but it relates to internal temperature maintenance, not evaporative cooling.
