Objective 1: From the First Law to enthalpy

Week 7 · Objective 1

Professor’s objective: “Derive H ≡ E + PV from the First Law for a system doing only expansion work, and explain why Q_P is a state function while Q in general is not.”

Build this argument one question at a time, starting with the First Law. The answer review will distinguish the state function from the heat transfer that equals its change under specified conditions.

1. Read each question and write your answer and reasoning on paper or in your own notes.
2. Keep your original answer intact. Do not erase or overwrite it.
3. Switch on “Reveal answer,” then separately record what you got right, what you got wrong, and what you left out.
4. Rewrite your answer underneath the original, staying as faithful as possible to your own wording while making the necessary corrections and additions.
5. Finish your reflection and rewrite, then select “Next question.” Earlier questions collapse and can be reopened. The “Compare, then revise” reminder is available inside each answer. The Key connections sidebar grows as you reveal answers.
