[QUOTE="diaaa2, post: 6243451, member: 668037"] [B]Homework Statement:[/B] A PV diagram shows an isobaric expansion, I'm asked to know the signs of: work done on, heat added to, and change in energy content of the system. [B]Relevant Equations:[/B] W= integral (P dV), dU = Q + W [B]Homework Statement:[/B] A PV diagram shows an isobaric expansion, I'm asked to know the signs of: work done on, heat added to, and change in energy content of the system. [B]Homework Equations:[/B] W= integral (P dV), dU = Q + W Since this is an expansion, the system does work on the surrounding and therefore the work done on the system is -ve. Also, to preserve a constant pressure, heat has to be added, therefore heat added is +ve. The energy content(dU) is the sum of those too, and since the process is isobaric not adiabatic, dU has a value. How can I know whether it is negative or positive? [/QUOTE]
