  1. Question 1

    Q1. A person sweats profusely during a marathon to maintain body temperature. Which property of water facilitates this cooling mechanism?

    • A) High specific heat capacity of liquid water
    • B) High latent heat of vaporization
    • C) Low density of ice compared to liquid water
    • D) High surface tension of aqueous solutions

    Answer: High latent heat of vaporization

    Explanation: Water's high heat of vaporization allows effective cooling through evaporation. High specific heat buffers temperature changes within the body.
