  1. Answer:

    Option (b) is correct.

    Explanation:

    The amount of heat required to raise the temperature of substance of mass 1 kg by 1 degree C, is called specific heat of the substance.

    The formula of the specific heat is

    H = m c (T’ – T)

    where, m is the mass, c is the specific heat and T’ – T is the change in temperature.

    So, to know the rise in temperature, by adding the known amount of heat, the specific heat is required.

    So, option (b) is correct.
