The pressure volume work for an ideal ga...

The pressure volume work for an ideal gas can be calculated by using the expression `w=-int_(V_(i))^(v_(f))Pex dV`. 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 volume `V_(i)` to `V_(f)` choose the correct option.

A

W (reversible) = W (irreversible)

B

W (reversible) `lt` W (irreversible)

C

W (reversible) `gt` W (irreversible)

D

W (reversible) = W (irreversible) `+ P_(ex). Delta V`

Text Solution

Verified by Experts

The correct Answer is:
B
The correct option is W (reversible) `lt` W (irreversible). This is because area under the curve is always more in irreversible compression as can be seen from given figure.
