  1. Question 1

    Q1. Water serves as a temperature buffer in organisms. This property is represented in diagrams showing minimal temperature change despite heat absorption, due to:

    • A) High specific heat capacity
    • B) High heat of vaporization
    • C) High surface tension
    • D) High solvent power

    Answer: High specific heat capacity

    Explanation: High specific heat allows water to absorb heat with minimal temperature change. Heat of vaporization is tempting but relates to cooling via evaporation.
