Expand 1.00mol of an monatomic gas initially at 5.00 kPa

Expand 1.00mol of an monatomic gas initially at 5.00 kPa and 600 K from initial volume V1 = 1.00 m3 to final volume Vf = 2.00 m3. At any instant during the expansion, the pressure p and volume V of the gas are related by p = 5.00 exp [(Vi – V)/a], with p in kilopascals, Vi and V in cubic meters, and a = 1.00 m3. What are the final?

(a) Pressure and

(b) Temperature of the gas?

(c) How much work is done by the gas during the expansion?

(d) What is AS for the expansion?
