A) \[\Delta U=0\] (isothermal reversible expansion of a gas)
B) \[w=-nRT\] In \[\frac{{{V}_{2}}}{{{V}_{1}}}\] (isothermal reversible expansion of an ideal gas)
C) \[w=nRT\] In \[\frac{{{V}_{2}}}{{{V}_{1}}}\] (isothermal reversible expansion of an ideal gas)
D) For a system of constant volume heat involved directly changes to internal energy.
Correct Answer: C
Solution :
For isothermal reversible expansion. \[w=-nRT\,ln\frac{{{V}_{2}}}{{{V}_{1}}}\]
