A 187 g piece of metal is rapidly removed from a furnace at a temperature of 600 °C and quenched in 1600 g of water. The initial temperature of the water is 25 °C.

If the final temperature of both metal and water reach 33 °C and knowing that the specific heat capacity of water is 4190 J kg-1 °C-1, calculate the specific heat capacity of the metal in J kg-1 °C-1, (to 1 d.p.).

Answer: Answer J kg-1 °C-1 (1 d.p.)
