Question

Please do not solve the question in the 2nd image.

From image 1,

Total entropy change:

Ssystem + Ssurrounding = Sisolated

What does it mean by Ssystem and Ssurrounding? Able to explain it using the question shown in the 2nd image? Is the question asking to find Ssystem or Ssurrounding?

i am able to obtain the answer by finding the Rate of Entropy change in the high Temperature side and low temperature side. But i do not know whether it is the entropy for the system or surrounding.

Total entropy change in this “isolated system" is

3. A completely reversible heat pump produces heat at a rate of 300
kW to warm a house maintained at 24 °C. The exterior air which is
24°C
at 7 °C serves as a source. Calculate the rate of entropy change of
the two reservoirs and determine if this heat pump satisfies the
second law according to the increase of entropy principle.
