SUMMARY
The discussion focuses on calculating the temperature of blood after it releases energy while flowing to the surface of the body during exercise. Given that 0.8 kg of blood releases 1300 J of energy and assuming its specific heat capacity is equivalent to that of water (cwater = 4186 J kg−1.°C−1), the temperature of the blood returning to the interior can be determined using the formula Q = mcΔT. The initial temperature of the blood is 37.0 °C, and the energy released affects its final temperature.
