Re: Zero work
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.

Re: Zero work
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!

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

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

Re: Zero work
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.

Re: Zero work
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!

Re: Zero work
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.
