Question
Imagine that a hypothetical life form is discovered on our moon and transported to Earth. On a hot day, this life form begins to sweat, and it is determined that the heat of vaporization of its sweat is 195 cal/g. The scientist observing the extraterrestrial life form also begins to sweat. The heat of vaporization of the scientist's sweat is 580. cal/g at the skin's surface. If both the extraterrestrial life form and the scientist lose 146 g of sweat over the course of one hour, calculate the heat lost by each body from the vaporization of sweat.
Explanation / Answer
extraterrestrial life form and the scientist lose = 146 g of sweat
heat of vaporization of its sweat = 195 cal/g
extraterrestrial = 146 x 195
= 28470 cal
heat lost by extraterrestrial = 28470 cal
heat of vaporization of the scientist's sweat = 580 cal/g
human = 146 x 580
= 84680 cal
heat lost by human = 84680 cal
