1. The problem statement, all variables and given/known data An alcohol rub can rapidly reduce an elevated body temperature in a patient. The heat energy lost by the person is due to the evaporation of alcohol. Find the number of grams of alcohol that must be evaporated from the surface of a 75 kg person to reduce the body temperature by 2.5 degrees C. The heat of vaporization for alcohol is 204 cal/g. The specific heat capacity of the human body is 0.83 cal/g degrees C. 2. Relevant equations It is a change of temperature problem and a change of phase problem so I am unsure as to the formula. Change of temp is Q=(mass)(specific heat)(change of Temp) and change of phase is Q=(mass)(latent heat) Can someone please help me determine which formula I am to use to solve? Thanks in advance for any assistance you can provide!
