Homework Statement
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.
