Question

4. A 120.0 g piece of metal is heated to 410oC and then dropped into an insulated container filled with 50.0 g of ice and 100.0g of water.

a) After the system reaches equilibrium, 5.0 g of ice remain in the calorimeter. Calculate the specific heat of the metal.

b) If the same procedure is followed with a different metal that has a specific heat of 0.115 cal/g oC , what will be the final temperature in the calorimeter?

++I calculated Part A and found that energy requried for melting the ice to be 15075 J, and the specific heat to be .0732 cal/g*C. But I'm having a difficult time solving Part B without the initial tempertature of the calorimeter.

Explanation / Answer

(m1.c1.t1+m1.c1.t2)/(m1.c1+m2.c2)=temperature of equilbrium If specific heat of water is 4.1813 then specific heat 1.07905
