1 Answer
The work done is 614.33 Joules.
Explanation:
When a gas expands at constant pressure then for a small change in volume
If the volume changes from
When work is done by the system against external pressure then
So, by calculating with given numericals we get,
To have the answer in terms of we use below units:
But
Substitute '
Now as we know
Converting the workdone
