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 295 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 508 g of sweat over the course of one hour, calculate the heat lost by each body from the vaporization of sweat.
Explanation / Answer
Heat lost by extraterrestrial life form from the vaporization of 508 g sweat=295 Cal/g *580 g=171100 Cal
heat lost by the scientist from the vaporization of 508 g sweat=580Cal/g*508 g=294640 Cal
