A copper forceps that has a mass of 500 g was accidentally left on a heating mantle until
it had a temperature of 35 ᵒC. A student then placed the forcep in 70 g of water at 22 ᵒC
to cool it off. Calculate the specific heat capacity of the copper forcep if the final
temperature of the water was 27 ᵒC. (Specific heat capacity of water is 4.18 J/°C. g).
