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 241 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 186 g of sweat over the course of one hour, calculate the heat lost by each body from the vaporization of sweat.

Answer 1

Total heat lost = 153450cal

Step-by-step explanation:

Assumptions:

1. both the hypothetical life form and the scientist lose 186g of sweat per hour each
2. all heat lost is due to vaporization of sweat

Heat Lost by Hypothetical Life Form

`Q=m*l`

`Q=186g*241cal/g`

`Q=44826cal`

Heat Lost by Scientist

`Q=m*l`

`Q=186g*580cal/g`

`Q=107880cal`

Total heat lost = 44826cal + 107880cal

Total heat lost = 153450cal
