A 220lb worker loses 8 pounds of sweat during the day. All of the sweat evaporates. How much heat will he lose through evaporation? (Hint. Convert all measures to metric)
Answered by drwls
8 lb = 3.632 kg = 3632 g of sweat

Heat of vaporization = 540 cal/g

3631*540 = 1.96*10^6 calories
= 1960 kilocalories
= 8.2*10^6 Joules
