    Answer:

    Heat capacity, Q = 2090 Joules.

    Explanation:

    Given the following data;

    Mass = 100 grams

    Specific heat capacity = 4.18 J/g°C.

    Temperature = 5°C

    To find the quantity of heat required;

    Heat capacity is given by the formula;

     Q = mct

    Where;

    Q represents the heat capacity or quantity of heat.

    m represents the mass of an object.

    c represents the specific heat capacity of water.

    t represents the temperature of an object.

    Substituting into the formula, we have;

     Q = 100*4.18*5

    Heat capacity, Q = 2090 Joules.
