A metal bolt with a mass of 8.50 x 10^-2kg and a temperature of 85.0 degrees Celsius is placed in a container of water. The mass of the water is 0.150 kg, and its temperature is 25.0 degrees Celsius. What is the specific heat capacity of the bolt if the final temperature of the bolt and water is 28.4 degrees Celsius? (Cp.w = 4186 j/k* degree Celsius)

The temperature of the water rises from 25*C to 28.4*C, that is 3.4*C so that the heat absorbed is the mass x change in temp x shc = 0.150 x 3.4 x 4186 =2134.86 J Now the bolt release the same energy To mass x change in temp x shc = 2134.86 J 0.085 x (85-28.4) x shc And shc = 2134.86 / (0.085 * 56.6) = 443 J/KgC
