3. A copper calorimeter whose mass is 250 g contains 700 g of water at 25 C. When 25 g of a certain metal at 98 C is immersed in the water, the resulting temperature is 30* C. What is the specific heat of the metal? The specific heat of copper is 0.093 cal/g Co. 4. If 8000 cal of heat is needed to change the temperature of a certain amount of ice at -25 C to steam at 135 C, determine the mass of the ice. The specific heat of ice is 0.50 cal/g Co while its heat of fusion is 80 cal/g. The specific heat of steam is 0.46 callg Co while its heat of vaporization is 540 cal/g
