A substance contained in a flexible, well-insulated container undergoes an expansion process from an initial state with a specific volume of 10 ft3 /lb and pressure of 12 lbf/in2 to a final state with a specific volume of 24 ft3 /lb. During the process, the substance’s pressure varies according to Equation 1 where pi is the substance’s initial pressure and vi is the substance’s initial specific volume. The substance’s internal energy decreases by 500 Btu during the process. Neglect potential and kinetic energy changes.

a. Determine the specific work done on the substance in Btu/lb.

b. Determine the mass of the substance in lb.

An insulated container contains a gas with some initial conditions. A lid is opened which allows the gas to pass into another insulated container which was initially empty. The mass of the gas remains constant. A process is described as reversible if there is no change in entropy. Explain in detail if this process is reversible or not.
