Exercise 95

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 °C 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.
