Question

A piece of copper ball of mass 20g at200 Is placed in a copper calorimeter of mass 60g containing 50g of water at 30 ignoring the heat loss calculate the final temperaure of the mixture

Answer 1

T is between 200 deg and 30 deg
heat out of copper = Cc * 20 ( 200-T)
heat into water = Cw * 50 (T-30)
they are equal

Answer 2

Good question
