Determine the change in the player's internal energy and the number of calories…..

A basketball player does 2.05*10^5 J of work during her time in the game, and evaporates 0.120 kg of water. Assume a latent heat of 2.26*10^6 J/kg for the perspiration(the same as for water).

a. Determine the change in the player's internal energy. delta U= _____kJ
b. Determine the number of nutritional calories the player has converted to work and heat. delta U=______kcal
