Answer: For the given amount of sweat lost, the amount of energy required will be 692,899 Joules.
Step-by-step explanation:
We are given:
Heat of vaporization for water = 2257 J/g
Amount of sweat lost = 307 grams
Applying unitary method:
For 1 g of sweat lost, the energy required is 2257 Joules
So, for 307 grams of sweat lost, the energy required will be =

Hence, for the given amount of sweat lost, the amount of energy required will be 692,899 Joules.
