Constant Vol.

[Steven Garcia 1H]

Does constant volume always imply that w=0 ?

[Samantha Kwock 1D]

Constant volume means that the change in volume is zero. Thus in the work equation, the overall work done would be zero as you would multiply pressure by zero. If volume does not change, then the system does no work,

[mahika_nayak_3L]

Constant volume means that work is zero because there is no change in the volume, so you know that there is no work of expansion being done within the system.

The equation for the work is Pext x change in volume, so if the volume is constant, the change in volume is zero therefore pressure is multiplied by zero which is w=0

[Rehan Chinoy 1K]

Since work (w) is equal to (pressure) * (change in volume), if there is no change in volume then work must be equal to zero.

[Brian Hom 2F]

When the volume is constant, this means that work equals zero because work=-PdeltaV and work=-nRTln(V2/V1). At constant volume, both of these equations lead to the work equaling zero.

[Jack Hewitt 2H]

Yes, when volume does not change work or "w" is equal to 0.

[Mark 1D]

Work is zero if no change in volume as there is no expansion or compression

[Luis_Yepez_1F]

Yes since if there is no change in pressure, then zero work would be done.
