Q377

Pick out the correct statement:

A.
In an isothermal system, irreversible work is more than reversible work
B.
Under reversible conditions, the adiabatic work is less than isothermal work
Answer
C.
Heat, work, enthalpy and entropy are all 'state functions'
D.
Matter and energy can not be exchanged with the surroundings in a closed system

Answer: Option B

Solution

Answer: Option B
Solution:
Under reversible conditions if we see the area under  plot the area is maximum in case of isothermal conditions hence the adiabatic work is less than isothermal work.
