A small metal object of mass m= 258-g and temperature Tm = 454-°C is dropped into V= 6.3-L of water at temperature Tw = 5.1-°C. This causes the temperature of the water to rise, so that the final equilibrium temperature of the water and metal object is Tf = 10.7-°C. What is the specific heat capacity of the metal? You may assume the specific heat of water to be 4186-J·kg-1·K-1and the density to be constant in the temperature range of interest.
