A 300 gm piece of metal is heated to 150° C and then dropped into an aluminum calorimeter of mass 400 gm, containing 400 gm of water initially at 25°C. Find the final equilibrium temperature of the system (specific heat of metal is 128.100 J/Kg-K, specific heat of aluminum is 903 J/Kg-K and the specific heat of water 4200 J/Kg-K
