One mole of nitrogen at 8 bar and 600 K is contained in a piston-cylinder arrangement. It is brought to 1 bar isothermally against a resisting pressure of 1 bar. The work done (in Joules) by the gas is
Answer & Solution
Correct Answer:
Option
B
Assuming ideal gas behavior the isothermal work done is given as :
\[\begin{array}{l} W = nRTln\frac{{{P_1}}}{{{P_2}}}\\ W = 1 * 8.321 * 2079\\ {\rm{So}},W = 10379,{\rm{nearly \, equal \, to }}\,W = 10373 \end{array}\]
\[\begin{array}{l} W = nRTln\frac{{{P_1}}}{{{P_2}}}\\ W = 1 * 8.321 * 2079\\ {\rm{So}},W = 10379,{\rm{nearly \, equal \, to }}\,W = 10373 \end{array}\]
