A basketball player does 2.43 X 105 J of work during her time in the game, and evaporates 0.110 kg of water. Assuming latent heat of 2.26 X 106 J/kg for the perspiration (the same as for water), (a) determine the change in the player’s internal energy, and (b) the number of nutritional calories the player has converted to work and heat.
First law of thermodynamics
U = Q-W
The Attempt at a Solution
I need help on how to start it and what they mean by latent heat. Thank you
