Two identical 1 kg blocks of copper metal one initially at a temperature T = oC and the other initially at a temperature T = 100C are enclosed in a perfectly insulating container. The two blocks are initially separated. When the blocks are placed in contact, they come to equilibrium at a final temperature T The amount of heat exchanged between the two blocks in this process is equal to which of the following? (The specific heat of copper metal is equal to 0.1 kilocalorie/kgK) A. 50 Kcal B. 25 Kcal C. 10 Kcal D. 5 Kcal E. 1 Kcal
