A closed, rigid, insulated vessel having a volume of 0.15 m3 contains oxygen initially at 10 MPa and 280 K. The oxygen is stirred by a paddle wheel until pressure increases to 15 MPa. Stirring ceases and the gas attains a final equilibrium state. Using the RG model (N-O charts), determine
(a) The final temperature (T2),
(b) Work done (W) during the process and
(c) The amount of availability destroyed in the process. Let T0 = 280 K.
