The pressure-volume work for an ideal gas can be calculated by using the expression
The work can also be calculated from the pV - plot by using the area under the curve within the specified limits. When an ideal gas is compressed (a) reversibly or (b) irreversibly from Vi to Vf, choose the correct option.
(i) w (reversible) = w (irreversible)
(ii) w (reversible) < w (irreversible)
(iii) w (reversible) > w (irreversible)
(iv) w (reversible) = w (irreversible) + pex.
The answer is option (ii) w (reversible) < w (irreversible).
Explanation: In the situation of irreversible compression, the area under the curve is always larger comparativel
