JEE Main & Advanced Physics Transmission of Heat Question Bank Topic Test - Transmission of Heat (3-5-21)

  • question_answer
    The rate of loss of heat from a body cooling under conditions of forced convection is proportional  to its [A] heat capacity [B] surface area [C] absolute temperature [D] excess of temperature over that of surrounding : state if

    A) A, B, C are correct         

    B) Only A and C are correct

    C) Only B and D are correct

    D) Only D is correct

    Correct Answer: C

    Solution :

    In forced convection rate of loss of heat \[\frac{Q}{t}\propto A(T-{{T}_{0}})\]
