Suppose we have a solid of temperature $T_s$ and heat capacity $C_p$ submerged into a pool of water that has temperature $T_w$.
If $T_s \gt T_w$ and the pressure of the isolated pool-solid system is constant, how much heat will the solid lose, how much heat will the pool gain and what will the entropy change be for every part?
Edit I do understand that the format of the question resembles that of a plain exercise. However, aid in a question as such will mostly help me understand what kind of a process this heat transmission is and how it could be described mathematically. That said, I have indeed worked on the question and reached a certain point of progress but would appreciate some help.
