  1. Question 1

    Q1. During a vigorous workout, a marathon runner's body temperature is regulated by sweating. Which property of water is responsible for this effective cooling?

    • A) High specific heat
    • B) High heat of fusion
    • C) Low density of ice
    • D) High heat of vaporization

    Answer: High heat of vaporization

    Explanation: High heat of vaporization allows significant heat loss with minimal water loss. Specific heat is tempting but refers to temperature stability.
