A piece of metal at a temperature of 384.12K was dropped into copper calorimeter of mass 0.1kg. The calorimeter contained 0.2kg of water at 303.62K. The final temperature reached was 303.14K. Determine the heat by the metal if its specific heat capacity is 0.479 x 103³ J.kg¹.K¹ (A) 14.5 x 10³J (B) 2.0 x 10³J (C)3.9 x 10³J (D) 18.4 x 10³J
