  1. Question 1

    Q1. A cell maintains a stable internal temperature despite rapid external fluctuations. Which property of water is primarily responsible for this thermal buffering?

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

    Answer: High specific heat capacity

    Explanation: Water's high specific heat capacity allows it to absorb heat with minimal temperature change, unlike heat of vaporization which relates to cooling.
