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, 0.671 kg of blood flows to the surface of the body and releases 1860 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 in degrees Celsius of the blood that leaves the surface and returns to the interior. Attempt From the equation: I get the change in temperature. Since I am given initial temperature all I need to do is take the change in temperature and add the initial temperature: (change)TEMP = Tf-Ti Problem: I'am not getting the right final temp.
