State Functions and Path Functions

In this video, we discuss the basic definitions of--and differences between--state functions (like internal energy and enthalpy) and path functions (like heat and work). A state function is a property whose value depends only on the current state of a system, not how the system arrived at that state. Path functions, however, do depend on the path taken to get to the current state of a system.

And finally I got my concept.great explaination,thx a lot..

[@sheristeele1]

This was awesome.. and you have a great sense of humor to make the learning enjoyable! THANK you.

[@sss23431]

I love how you explained the difference between changes of energy! I was always confused of the differences between negative and positive, but I now really get it! thank you soooo much!!!

[@lizmorgan6637]

thank u ben chem for existing

[@mirjafar48]

Ben u are like a weapon for me which i can use to beat everyone

[@niroos6819]

thank u sooo much everything is so much more clearer now awesome explanation!!

[@sylviemuhimpundu9634]

Thank you for the video! I have 2 questions, 1. Why is work equal to the final KE? Shouldn't work equal to the change in KE instead? 2. Would you say that a conservative work (no friction, no air resistance, etc) exhibit state function properties?

If food can be converted into thought and so the resverse should be possible or not and if not what prevent it?

[@vanithar7459]

Explained well...👍

Wow Saved my Day !! Thanks Buddy

[@srinivasethiraj4979]

Wowie! Thanks buddy (y) Explained so beautifully!

[@TheZmoliver]

Why does everything else on the internet say that q and w are path functions, not state functions. Am I just misunderstanding the way you're explaining it? Thank you.

[@BensChemVideos]

q and w are path functions

[@janlukasr.2141]

Wonderful explanation, thanks a lot :)

No offence but why to inidan people always put a sir in the and? i mean its nice and stuff but isn't it kinda oldfashion?

Heat is state function why

[@BensChemVideos]

No, heat is a path function

[@Alejandro-ru4un]

Isn't U a more common symbol for internal energy than E??

[@BensChemVideos]

My general chem textbook used "E", but my physical chem textbook used "U". If/when I get around to making physical chem vids, I'll use "U". Thanks for your feedback and for watching!
