Lecture 18 Figure inconsistency #3
Description
In lecture 17 and in the first figure of lecture 18, when work is being done by the system, the delta W term is drawn with an arrow out of the heat engine. For figure 3 and 5 (both the BAC and BCA examples), the delta W term is drawn with an arrow in when work is being done by the system, where previously it would be drawn as an arrow out. For figure 3, the delta W1 term should be going out of E1. For figure 5, the delta W term for both engines should be pointing out.
