Please show an explanation while solving. Don't post old solutions unless they are for the same exact question with similar values. Thanks in advance.

- A Piston-cylinder device initially contains 1- KgH2O as SAT liguid at ISo KPa? When the Piston sitson the sto Ps, heat is transferred to water. The P float =200KPa When the Piston touches the spring, enclosed vol. is 0.4m3. Heat transfer till P=300KPa&T=200C Draw a P-V diagram \& find entropy generotion
