NEETChemistryThermodynamics (C)
Consider the reversible isothermal expansion of an ideal gas in a closed system at two different temperatures T 1 and T 2 T 1 < T 2 . The correct graphical depiction of the dependence of work done w vs the final volume V is:
Correct answer
3
Step-by-step solution
w = - nRTln v 2 v 1 w = - nRTln v f v i w = nRTln v b v i w = nRT ln v f - ln v i w = nRTln v f - nRTln v i y = mx - c So for T 2 > T 1 Intercept of T 2 would be more negative than T 1 and slope of curve T 2 would be more than slope of curve T 1 .
