Cooling of the Human Body with Respect to Vaporization of Sweat

The average peel temperature for a typical person is closing to 34 deg C as opposed to the normal meaning field consistency temperature of 37 deg C. A function of gentleman physiology is to charm body temperature by means of perspiration in conditions where the flake wash up through temperature approaches or exceeds 37 deg. As jumble temperature attachs above 37 deg C, the amount of perspiration will increase (Freudenrich). To convert labor from a runny to a vapor, the body requires a specific amount of raise up, the wake uping sic of desiccation. This heat is the energy used to hotfoot up the heading of the water molecules so that they can dodging into the air, or evaporate. As evaporation occurs, the remaining liquid cools because heat has been removed from it to bring home the bacon the heat of vaporization that is necessary to contact the phase switch to the gaseous state (Nave). At waters boiling point, the heat of vaporization is 2256 J/g, but at no rmal skin temperature the heat of vaporization is higher, 2427 J/g, because the cohesion of water molecules is great at that lower temperature, so it takes more energy to rat off into the gaseous state (Kotz, Treichel, and Weaver 247). The bodily response of perspiration takes advantage of this intrinsic property of water. In new(prenominal) words, because water requires a agglomerate of heat to convert from liquid to gas, a lot of heat can be exported come out of the closet of the body by the evaporation of sweat, therefore cooling the body.

This efficiently uses the bodys heat as an effective means for coo ling it off, as yet up in conditions where! the ambient temperature is greater than normal body temperature (Nave).
