A 20.0 g piece of copper at 100 Celsius degrees, is placed in a vessel of negligible heat capacity but containing 50.7 g of water at 33.O Celsius degrees. Calculate the final temperature of water. (Hint: use the law of the conservation of energy to write a relation in which the energy lost by the copper is equal to the energy gained by the water). C Cu= 0.385J/gC, C H2o= 4.18J/gC
