Question by : It is important for the body to have mechanisms to effectively cool itself?
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 24 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?

They are basically asking how much hotter 70kg of water will get if you dump 24*60*1000 joules of energy (heat) into it without letting it cool by conduction, convection or radiation.

Rise in temperature, t = [1000*60*24/4.18]/70000 deg C assuming p heat of human material = 1 cal/gram per degree C or
t = 4.92 degree Celsius
