I just wanted to double check if my train of thought was correct on this one:

Is the heat negative on the 800K reservoir because the process is taking heat from that reservoir and giving it to the 200K reservoir?
If not, why is it negative?

The heat is negative because 40.0 kJ of energy is being transferred from a large reservoir to another reservoir.

Since the problem says that the heat is being transferred from one reservoir to another, you can assume that the heat is leaving the first reservoir (-q) and entering the second reservoir (+q).

So would the signs be the same for entropy as well?
