    The answer to your question is Q = 355.64 J

    Explanation:

    Data

    Heat = Q = ?

    Temperature 1 = T1 = 20°C

    Temperature 2 = T2 = 37°C

    mass = m = 5 g

    Specific heat = Cp = 4.184 J/g°C

    Formula

    Q = mCp (T2 - T1)

    -Substitution

    Q = (5) (4.184) (37 - 20)

    -Simplification

    Q = (5) (4.184) (17)

    -Result

    Q = 355.64 J
