An unknown metal of mass 192 g heated to a temperature of 100∘C was immersed into a brass calorimeter of mass 128 g containing 240 g of water at a temperature of 8.4∘C. Calculate the specific heat of the unknown metal, if water temperature stablizes at 21.5∘C.(Specific heat of brass is 394 J kg−1K−1)
