... Step 3: Involves isobaric cooling. Where only the volume of gas decreases as the vapor is cooled. ΔE3=q3 +W=CVp(T1-T2)-P(VT2-VT1) ; ΔH3=ΔE3+Δ(PV)=q3 This shows how an irreversible process can be broken down in terms of series of reversible processes and hence we can calculate associated changes in t ...

... Two closed thermodynamic cycles for an ideal gas are depicted on the pV diagram. Imagine processing the gas clockwise through Cycle 1 once. Determine whether the change in internal energy of the gas in the entire cycle is positive, negative, or zero. • ΔU1clockwise = 0 internal energy only depends o ...
