Question:

Blood can carry excess heat from the interior to the surface of the body, where the heat is transferred to the outside environment. If 0.250 kg of blood at a temperature of 37.0 oC flows to the surface and loses 1500 J of heat, what is the temperature of the blood when it flows back into the interior? Assume blood has the same specific heat as water.
