Work of the system

Postby Katie Frei 1L » Wed Feb 13, 2019 10:58 am

When can you assume that the work of the system equals zero, or when no work is done?

You can assume that the work of the system is zero when the system is at constant pressure and is not changing volume.

You can assume the work of the system is zero when there is no change in volume, given that w=-pdeltav. Therefore w would equal zero since deltav equals zero.

You can assume work is equal to 0 in a vacuum where the external pressure is 0
