A basketball player does 1.85 multiplied by 105 J of work during her time in the game, and evaporates 0.170 kg of water. Assuming a latent heat of 2.26 multiplied by 106 J/kg for the perspiration (the same as for water) determine each of the following.
(a) the change in the player's internal energy __kJ
What I did is:
Delta u=Q-W = 2.26x10^6 - 1.85^5/0.170kg = 1171.76
(b) the number of nutritional calories the player has converted to work and heat? ___ kcal
I am very clueless!
