A basketball player does 2.45×105 J of work during her time in the game, and evaporates 0.110 kg of water. Assume a latent heat of 2.26×106J/kg for the perspiration (the same as for water). Determine the number of nutritional calories the player has converted to work and heat.

A basketball player does 5.17×105 J of work during her time in the game, and evaporates 0.141 kg of water. Assume a latent heat of 2.26×106J/kg for the perspiration (the same as for water). Determine the change in the player's internal energy. Thank you in advance

Help!!!
Part A If a total of 5.55 x 10% J of heat is added to a mass of 555 g of water which was originally at a temperature of 555°C (and noting that the specific heat of water is 4186 J/kg-K and that the latent heat of vaporization of water is 2.26 x 106 J/kg), then what is the mass of the water that remains (ie. the mass of the water that was not vaporized)? O 335 g 258...
