to think that lenz law would only be tested as a definition, only to find all these papers that test the intuition about the law itself! Insane! Thanks for the video, and the clarification at the end especially.

how is the numerator increasing in 33:50 when the pressure increases? Shouldn't it be getting smaller instead cuz it is U -- PV, not U + PV

Q3c Latent heat of vaporisation decreases with increase in pressure ( you proved otherwise) .
Lets consider pressure is critical, than latent heat becomes zero.
Any thoughts?
I came specifically for this question.
