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)

  • physics -

    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
