Five moles of an ideal gas expands isothermally at 97degreeC to four times its i

Question

Five moles of an ideal gas expands isothermally at 97degreeC to four times its initial volume. The work done by the gas is (R = 8.31 J/mole-kg) 4.9 times 10^6 J 3.4 times 10^5 J 1.9 times 10^4 J 2.1 times 10^4 J A process in which no heat is exchanged with the surroundings of a system is described as a isothermal isobaric isometric adiabatic The work done in the expansion of a gas from an initial to a final state is always equal P(V_l - V_i) depends only on the end points is independent of the path is the area under the curve of a PV diagram The thermodynamic property which gives the directionality of a process is entropy internal energy thermal efficiency Carnot efficiency

Explanation / Answer

4) Option D)

Work done in isothermal expansion = W = nRT*ln[Vf/Vi]

                                      W = 5*8.314*370*ln[4] = 2.1*10^4 J

5) Option D) Adiabatic

6) Option D)

Work done is the area under the curve of a PV diagram.

7) Option A)
