A piece of copper ball of mass 20g at 200 degree centigrade is placed in a copper calorimeter of mass 60g containing 50g of water at 30 degree centigrade. Ignoring heat losses calculate the final temperature of the mixture

Answer 1

20 * 377 * (200 - t) = [(50 * 4190) + (60 * 377)] * (t - 30)

Answer 2

35.6° c
