(%25) Q1. A tank is perfectly insulated and divided into two parts by a membrane. The first part occupies 5 m³ volume containing air at 100 kPa pressure and 300 K temperature and the second one 2 m³ air at 2 MPa and 300 K. The membrane suddenly raptures somehow, and then thermodynamic equilibrium is established. (a) Find the final temperature, pressure and entropy change of air, (b) Calculate the entropy generation during this process.
