    Consider two identical iron spheres P and Q, one which lie on a thermally insulating plate, while the other hangs from an insulated thread. Equal amount of heat (AQ) is supplied to the two spheres. Then,

    A)  the temperature of Q will be greater than P

    B)  the temperature of P will be greater than Q

    C)  their temperature will be equal

    D)  cant be predicted

    Correct Answer: B

    Solution :

     Heat transferred between two bodies depends upon the common area of contact between the two bodies. In case of Q area of contact is more. Thus, heat transferred for Q is more. Thus, temperature of Q is lesser than P for same amount of heat gain.
