Real Gas P-v-T relation - GATE ME '05
Nitrogen at an initial state of 10 bar, 1 m3, and 300 K is expanded isothermally to a final volume of 2 m3. The p-v-T relation is (p+a/v^2)v=RT, where a>0. The final pressure _______ A. will be slightly less than 5 bar B. will be slightly more than 5 bar C. will be exactly 5 bar D. cannot be ascertained in the absence of the value of a.
