Question

magine 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 285 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 841 g of sweat over the course of one hour, calculate the heat lost by each body from the vaporization of sweat.

Explanation / Answer

heat of vaporization of its sweat = 375 cal/g.

extraterrestrial = 224 x 375 = 84000 cal

                                             = 84 kcal

The heat of vaporization of the scientist's sweat = 580. cal/g

scientist lose of sweat = 224 g

human = 224 x 580 = 129920 cal

                                = 129.9 kcal
