In one of your rigorous workout sessions, you lost 140 g of water through evaporation. Assume that the amount of work done by your body was 3.8 105 J and that the heat required to evaporate the water came from your body.
(a) Find the loss in internal energy of your body (due to evaporating water only), assuming the latent heat of vaporization is 2.42 106 J/kg.
(b) Determine the minimum number of food calories that must be consumed to replace the internal energy lost (1 food calorie = 4186 J).
help please!
