## Work without change in volume

$w=-P\Delta V$
and
$w=-\int_{V_{1}}^{V_{2}}PdV=-nRTln\frac{V_{2}}{V_{1}}$

### Work without change in volume

How can you find work at a constant temperature when there is no change in the volume?

(If I understand you correctly)

In the case when the system is isothermal (constant temperature) and the system is under constant pressure, work can be defined as the external pressure times the change in volume. If there is no change in volume, no work is done.

as work is equal to -PdeltaV and there is no change in volume, the expression would equal zero and no work is done.

If there is no change in volume, no work will be done. If you are referring to an isothermal process with constant pressure, then I'm pretty sure work = -(external P)(Delta V).

if there is no change in volume then there cannot be any work done. remember, it doesnt matter how hard you push against the wall, if it doesnt move no work was done.

### Re: Work without change in volume

If there is no change in volume, that means that the system has not expanded or been compressed. If there is no expansion or compression, there is no work because the work that we are referring to is only expansion/compression work.

### Re: Work without change in volume

There is no work done as there is no change in volume.

No change in volume means no work is done.

### Re: Work without change in volume

since there is no delta v , your delta v would be 0 so your overall work would also be 0
