Homework Help: Heat capacity temperature of blood

  1. Mar 27, 2010 #1
    1. The problem statement, all variables and given/known data

    Blood can carry excess energy from the interior to the surface of the body, where the energy is dispersed in a number of ways. While a person is exercising, 0.8 kg of blood flows to the surface of the body and releases 1300 J of energy. The blood arriving at the surface has the temperature of the body interior, 37.0 °C.
    (Note: cwater = 4186 J kg−1.°C−1)
    Assuming that blood has the same specific heat capacity as water, determine the temperature of the blood that leaves the surface and returns to the interior.

    2. Relevant equations

    3. The attempt at a solution
