Question

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, 0.7 kg of blood flows to the surface of the body and releases 2400 J of energy. The blood arriving at the surface has the temperature of the body interior, 37.0°C. 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.

Answer 1

Take 2400J and divide by 0.7 Kg then divide by the specific heat. That is the temperature drop. Subtract it from 37.0°C to get the final temperature.
