    To determine the heat required to raise a body's termperature by a certain number of degrees C, we use the equation,

    H = mcpdT

    where m is mass, cp is specific heat, and dT is the temperature difference. Substituting the known values,

    H = (30.0 g) (0.90 J/gC) (75 - 25)

    H = 1350 J

    Thus, there is a need for 1350 J of heat for the process.
