Consider two blocks. The initial temperature of block 1 is 280 K and the initial temperature of block 2 is 340 K. The heat capacities of blocks 1 and 2 are 400 J/K and 200 J/K, respectively.

A. The two blocks are placed in thermal contact with one another but are perfectly insulated from the remainder of their surroundings. We will call the process that begins when the blocks are brought in contact with one another process A.

Determine the final temperature of the two block- The final temperature is 300 K

1. Is process A allowed by the first law of thermodynamics? Explain your reasoning.
2. What is the total change in entropy of the two-block system during process A?
