Homework Statement



How large is the mass of sweat (water) evaporated by a man with 80 kg body weight assuming that his body
temperature decreased due to the evaporation by 1 °C? (Assume, that the human body consists mostly of water
and the heat of evaporation of water at body temperature (37 °C) is around 2400 J/g) (14 dkg)

Homework Equations



Q = Lm

c = ∆Q ÷ m∆T

The Attempt at a Solution



Many, so far. But I have no idea which variable for mass to use in which equation. I have almost no time left and need help quickly! The best would be a step-through-step.
