So you are saying there "is" such a thing as a free lunch :) You know cause double negatives makes a positive. I think you mean "There is no such thing as a free Lunch" I still gave it a thumbs up cause I'm here for chemistry.

In my textbook we use internal energy sign as U

Both are acceptable, as annoying as that is. My general chemistry textbook uses E, and my physical chemistry textbook uses U 🤷‍♂️

HI, can I ask why other sources use the equation delta U = Q - W instead of delta E = Q + W what's the difference, I hope you will notice... Thank you,,,, and does the definition of internal energy on your video will change then?? if it is delta U?

Good question! My general chemistry textbook calls it E, and my physical chemistry textbook calls it U. As far as I know, it's the same property--internal energy. I used E because I'm approaching it from an introductory, general chemistry point of view. It's unfortunate. Chemistry can be confusing enough as it is, but it's even more confusing when there are two different symbols to represent the same property. Hope that helps! 😀 -BeN
