A good example is a compression stroke of a piston. Everything inside the system is allowed to change - temperature, pressure, volume, but nobody gets out. You've heard of these but they might not have really clicked yet.Īdiabatic - Energy does not leave the system (corollary - mass doesn't leave either). If you make the right assumption, then you can be right to within decimals of real values.
So we use various conditions here and there to make it easier. Thermo is hard, and I mean hard when you don't set conditions or boundaries. Knowing how it's stored, what it's currently doing, what it's capable of doing, how much is wasted, how much we can prevent from being wasted etc. Thermo is all about balancing energy in a system. Hopefully as a relatively successful Chem Eng alumni (stupid amounts of thermo work) I can be helpful by breaking the basics of thermo down to easier to understand concepts. It takes a while to click for everyone, but once it clicks it clicks hard. Meme posts made outside this time will be removed.

If the topic of your post is currently covered in one of the megathreads/stickied posts at the top of the page, please put your content as a comment there instead. Not reading them and then complaining will not earn you any sympathy. This is a place for engineering students of any discipline to discuss study methods, get homework help, get job search advice, and find a compassionate ear when you get a 40% on your midterm after studying all night.
