Select the incorrect statements from the following.
A. The standard value of absolute entropy of elementary substances is taken as zero.
B. Work done is isothermal expansion is greater than that in the adiabatic expansion for same increase in volume.
C. During adiabatic expansion of a real gas, there is no change in the enthalpy of the system.
D. Expansion against vacuum is very large and hence, work done is also very large.
E. The condition for free expansion of an ideal gas under adiabatic conditions is 
and

Among the given statements, statements A and D are incorrect while the statements B, C
and E are correct. The correct form of A and D are
• The standard value of absolute entropy of elementary substances is not zero. It has a definite value.
• During expansion against vacuum, 
, so work done is zero.
