7. Calorimetry A piece of metal has mass 100 grams and an initial temperature of 100'C. lt is placed in an insulated container of mass 200 grams which contains 500 grams of water at an initial temperature of 17 .3"C. The container is made of the same material as the metal sample. lf the final temperature is 22.7'C, what is the specific heat capacity of this metal? How many calories ('1 cal = 4.186 J) are required to warm the metal sample by 10 degrees C?
