Pressure of system $>$ External pressure

Vedclass · Answer

(A) Work done by the system on the surroundings is given by the expression $w = -P_{ext} \Delta V$.
For the system to perform work on the surroundings (expansion),the volume must increase $(\Delta V > 0)$.
This expansion occurs when the internal pressure of the system is greater than the external pressure $(P_{sys} > P_{ext})$.
Therefore,energy is transferred as work from the system to the surroundings when the system pressure is greater than the atmospheric (external) pressure.
