We derived this equation in the previous lesson.
In this lesson, we will apply this equation to a variety of important, practical systems.
These systems are the building blocks of all of the important cycles that we will study later in this course.
Each application in this lesson involves different simplifications of the 1st Law, but all of the systems in this lesson have one thing in common: they operate at steady-state.
