Question

The pressure-volume of varius thermodynamic processes is shown in graphs:

Work is the mole of transference of energy. It has been observed that reversible work done by the system is the maximum obtainable work w text rev >w text irr The works of isothermal and adiabatic processes are different from each other w text isothermal reversible =2.303 n R T log 10((V2/V1)) =2.303 n R T log 10((P2/P1)) w text adiabatic reversible =CV(T1-T2) If w1, w2, w3 and w4 are work done in isothermal, adiabatic, isobaric, and isochoric reversible processes, respectively then the correct sequence (for expansion) would be (A) w1 < w2 < w3 < w4 (B) w3=w2=w1=w4 (C) w3< w2< w4< w1 (D) w3 > w1 >w2 > w4

w= Work done = Area under curve

$w_{1} < w_{2} < w_{3} < w_{4}$

$w_{3} = w_{2} = w_{1} = w_{4}$

$w_{3} < w_{2} < w_{4} < w_{1}$

$w_{3} > w_{1} > w_{2} > w_{4}$

$w =$ Work done $=$ Area under curve

w1​<w2​<w3​<w4​

w3​=w2​=w1​=w4​

w3​<w2​<w4​<w1​
