Draw the path in the pV diagram for an isobaric expansion from a volume of 2 m^3 to 5 m^3.



Idk which of these equations are needed cuz they all are given with this section...
ΔU=Q-W
ΔU=Q+W
W=PΔV
ΔU=Q
W=nRTln(Vf/Vi)
Q-W
ΔU=-W
ΔU=+W
e=W/Qh=1-Qc/Qh
e=1-Tc/Th
ΔS=Q/T




My attempt...

Graph with x being Volume and y being Pressure, a horizontal line from 2-5

An isobaric expansion means that the pressure is kept constant during the expansion. This means that when you graph the expansion on the pV diagram, you will have a line parallel to the V axis.
So what you did was right...
