please answer fast and use generalized charts

[4] [6] [5] [5] 14. [20 Marks ] (Use the Generalized Chart provided to solve this problem): A container has two compartments of equal volume, one containing 1 kg of methane at 9.3 MPa and 250 K and the other compartment is completely evacuated (State 1). A valve connecting the two compartments is fully opened and the methane expands throughout both compartments. During the process, 500 kJ of heat is transferred to the surroundings. The final state of the methane is saturated mixture at a pressure of 1 MPa (State 2). (a) Determine the final temperature of the methane (in K)? (b) What is the quality of the saturated mixture? (c) What is the enthalpy change (in kJ) as the system goes from State 1 to State 2? (d) Determine the entropy generated (in kJ/K) during the process if the temperature of the surroundings is 200 K. Data for methane: R = 0.5182 kJ/kg.K Tcr = 191.1 K Per = 4.64 MPa Cp = 2.254 kJ/kg.K
