Two copper blocks, each of mass 1.25 kg, one at 54°C and the other at 0eC, are placed in contact in an isolated container (so no heat can escape) and allowed to come to equilibrium. Calculate the final temperature of the two blocks (in K), the entropy change of each (in נ-K 1), and AStot (in נ-K 1). The specific heat capacity of copper is 0.3853-K 1-g 1 and may be assumed constant over the temperature range involved final temperature...

HELP!! ASAP please
2. Imagine that we have two large copper blocks, A and B, which are isolated from the surroundings. Block A is at a temperature of 250 K, and block B is at a temperature of 300 K. As the blocks are large, we can assume that a small amount of heat flowing into or out of them is reversible, and that such a process will not change the temperature of the block. It therefore follows that for...

FR 5. (15 points) Two blocks one of aluminum (Al MM= 26.98g/mol , Cp,m=24.35 J/mol K), the other of silver (Ag MM= 107.9 g/mol , Cp,m 25.351 J/mol K) of mass (100 g) are at two different temperatures (TAI=300K and Tag=500K). Calculate the change in entropy for the system once the final temperature is achieved.
