Sweat endothermic
Spletyes. due to evaporative cooling. the sweat gets vaporized from the skin into the atmosphere, by taking in heat from the body. (endothermic reaction to vaporize the sweat). thus the body cools down as it loses heat. this is why on a humid day you get hot and sticky, since the sweat cannot evaporate into the already saturated air. therefore, it … SpletSweat cools the body because evaporation is an endothermic process: H_2O (l) to H_2O(g) Delta H degrees_{rxn} = +44.01 kJ Estimate the mass of water that must evaporate from the skin to cool the body by 0.55 degrees C. Assume a body mass of 95 kg and assu; How much heat is absorbed if 45 grams of sweat is evaporated from someone's skin?
