I remember reading the first year thermo textbook for electrical engineering like 7 times on internal energy and still didn't fully understand until I watched this. Thank you!
Alright, I just noticed the smiley face in the "o" he did on accident in the word "done" at time #t=13m15s. If you noticed this or just now saw it, thumbs up!
Not sure how to apply this lesson to my overall question? I will have to think about it and formulate questions based on those thoughts. Thanks for the lesson!!
I just really like you and your videos man!

Sal,
If you assume Q=0 and W=0 doesn't it make sense to use the delta?

OH THANKS GOD GOD YOU WERE BORN!! you have a wonderful method if i continue watching your videos i can Guarantee the A+....... ! :D

You could use the expression delta U = Q-W with the following convention:
Q is + if it is added to the system
Q is - if it is removed from the system
W is + if it is done by the system
W is - if it is done to the system.

@alpazmar Work done by the system is energy lost, therefore W is - if it is done by the system.

My chemistry teacher does not even begin to compare to your outstanding method of teaching. Clear, precise, and easy to understand.
Thank you so much

Q = Energy gained by the system.
W = Energy lost from the system.
U = Total energy of the system before losing or gaining energy.

enthalpy is essentially a way of measuring how much heat is in a system! 6:10 Does not that contradict what you were just saying?
