It is important for the body to have mechanisms to effectively cool itself; if not, moderate exercise could easily increase body temperatures to dangerous levels. suppose a 70 kg man runs on a treadmill for 39 min , using a metabolic power of 1000 w. assume that all of this power goes to thermal energy in the body.

if he couldn't perspire or otherwise cool his body, by how much would his body temperature rise during this exercise?
