As an athlete exercises, sweat is produced and evaporated to help maintain a proper body temperature. On average, an athlete loses approximately 443 g of sweat during an hour of exercise. How much energy is needed to evaporate the sweat that is produced? The heat of vaporization for water is 2257 J/g.

999851 Joules of energy is needed to evaporate the sweat that is produced

Explanation:

Latent heat of vaporization is the amount of heat required to convert 1 gram of liquid water to gaseous form at its boiling point.

Given:  The heat of vaporization for water is 2257 J/g.

Thus if for 1 g , the heat required is = 2257 J

For 443 g , heat required is =

Thus 999851 Joules of energy is needed to evaporate the sweat that is produced

answer: h+ its less than oh
