I'm currently working on problems comparing [tex]\Delta[/tex]E to [tex]\Delta[/tex]H (in reaction systems and physical processes) and I'm having a bit of a hard time understanding the actual difference between the two. I know what each is, and I realize that they're completely different (although dependent of each other). I can recite their definitions but I'm not sure how to think of one as opposed to the other in terms of real life application. I was wondering if anyone could explain this difference better than my textbook. Any help is appreciated.
