A mass of 317.6 g having unknown composition is heated in an oven to a temperature of 307.61 °C. The mass is then dropped into the strong insulated calorimeter having 804.9 g of water. The initial temperature of water is around12.07 °C. The final equilibrium temperature of the system is around 17.19 °C. Suppose that the mass and water are in an isolated system and the water doesn’t vaporize. No heat is transferred to the water throughout this experiment. The specific heat of the water is around 4190 J/kg-K. Find out the specific heat of this unknown mass?
