Lecture 03, concept 10: Helmholtz vs. Gibbs free energy

why do we call them Helmholtz free energy and. Gibbs free energy? They do have dimensions of energy alright. What is so 'free' here?

Thank you.

Thank you!:)

Helmholtz free energy. Constant temperature and constant volume for a Closed System. Is this possible for ideal gas? If it is then,

PV = nRT
Constant V and T and also constant n (cause no mass transfer for closed system), hence constant P?

That squeaking is a total distraction for any vibrant mind.

But I still do not understand it physically..🙄

The video was beautiful.

Can we say a system energy+ energy from outside is helmotz and system energy+energy done for existence+energy from outside is gibbs

A pain in the "A"? Why not just say "ass"? You're just making it worse by censoring yourself. There is nothing shameful about saying ass; everybody has one.

"Astronomically stupid"? You just offended everyone who didn't already understand that G should not also be called F. I think a lot of people who are not so well read into the subject would maybe make that mistake, and I think it's unnecessarily harsh to call them astronomically stupid. It brings shame on them, and I have a feeling that probably reflects some shame you carry inside of you.

Don't be so harsh on yourself or on other people. It's unnecessary, and it prevents you and other people from expressing yourself fully, because of fear of being judged, which in turn impedes development. Beside, shame actually increases the risk of mental health issues like depression and anxiety, so if you want to make someone mentally unhealthy, you should shame them by calling them astronomically stupid or shame them for saying "ass."

Wouldnt that usually be called a closed system?

Thank you, great explanation.

anyone curious how he is writing their or where he is writing
let me kow plz

'good, i have it nailed down!'

but which F did you use?
XD

The instructor drew a "closed" system, not an "isolated" system. An isolated system does not exchange energy with its surroundings.
