LA 75 kg person cannot go out for a long time due to Covid-19 restrictions. That's why he rides a bike at home to keep his weight stable. During bicycling, his body produces energy at a rate of about 450 W due to metabolism, 80% of which is converted to heat. The person's body gets rid of all this heat by evaporating water (sweat). How many grams of water must the person's body evaporate in an hour? The heat of vaporization of water at body temperature is 2.42 x 10^6 J/kg.

Question
A 75 kg person cannot go out for a long time due to Covid-19
restrictions. That's why he rides a bike at home to keep his weight
stable. During bicycling, his body produces energy at a rate of about
450 W due to metabolism, 80% of which is converted to heat. The
person's body gets rid of all this heat by evaporating water (sweat).
How many grams of water must the person's body evaporate in an
hour? The heat of vaporization of water at body temperature is 2.42 x
10^6 J/kg.
