Zero work

[Samuel Mushinski 2G]

How can you tell when a system does zero work?

[emily3L]

When the volume is constant.

Furthermore, a system does zero work in free expansion or when it expands into a vacuum, in the case of a gas. Also, a system does zero work if the system is composed of a rection in a bomb calorimeter, in which the volume remains constant.

Like previously mention by our peers, there is zero work when volume is constant.

Hi!

If a reaction does not increase in volume and produce more moles of gas in products than in reactants, then that reaction does no work. This is because work is w = P * deltaV and if there is no change in volume then deltaV is zero and the work is also zero.

Hope this helps!

You can tell when a system does zero work when the volume is constant.

[Aeson Salcedo 3L]

There would be Zero work when there is no change in volume

[Yalit Gonzalez 1A]

There's zero work done when the volume is constant. Think about the piston example that Professor Lavelle gave in class, that might help.

Zero work is done when the volume is constant!

[Allie Kinsey 3H]

I believe that if a reaction occurs then there will always be work done.

[Emily Lam 2H]

If the displacement of the object is 0 then the system does zero work.

[Anabelle Pham 2C]

There is zero work when the volume is constant.

[Emma Fernandez 1C]

This would be when there is constant volume.

[Joyce Lee 1K]

Hello, it is easy to tell when there is zero work since the volume would remain constant.

[Tony Wu 2D]

The system does zero work if there is no change in volume.

[Maggie_Harned_3H]

Constant volume is an indicator of zero work being done on a system.

[Fiorella Garcia 3D]

You can tell when a system does zero work when the volume is constant since the equation for work = -P times delta volume and if the delta volume is zero then the work is zeo.

[Briana Gilman 1F]

when the volume is held constant, zero work is done

[Daniel Adolfo 2L]

When vvolume is constant, zero work is done

[Kirsten Yu 2K]

Zero work is done when volume is constant

[Mariet Garcia 1E]

Work will be zero when there is a constant volume.
w=-pdV
since there is a constant volume, dv will be 0 because there is no change once you multiply 0 with P we get w=0 hope this helps!

[Alec Villarreal 2H]

When the volume of a system is constant, then work is neither being done on nor by the system and so work would be 0.
