The First Law of Thermodynamics: Internal Energy, Heat, and Work

In chemistry we talked about the first law of thermodynamics as being the law of conservation of energy, and that's one way of looking at it, but physicists like doing math more than chemists do, so let's talk about the first law in terms of an equation. You like equations by now, don't you? You should!
