Statement of a problem № 10547


When perspiration on the human body absorbs heat, some of the perspiration turns into water vapor. The latent heat of vaporization at body temperature (37 °C) is 2.42 × 106 J/kg. The heat absorbed is approximately equal to the average energy E̅ given to a single water molecule (H2O) times the number of water molecules that are vaporized. What is E̅?
