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
