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

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(By Examveda Team)

Under reversible conditions if we see the area under $$P-V$$  plot the area is maximum in case of isothermal conditions hence the adiabatic work is less than isothermal work.
