Ch 4 - The First Law of Thermodynamics: Closed Systems

Here we present a discussion of the definition of work. We will briefly consider the following forms of work: boundary, shaft, gravitational, electrical, accelerational, and spring.

Here we present a discussion of the definition of heat. We will briefly consider the three mechanisms for heat transfer: conduction, convection, and radiation.

In this lesson, you learn about the first law of thermodynamics, also known as the conservation of energy principal. The first law is applied first to an adiabatic, closed system and then to a non-adiabatic, closed system.

Here we learn to use a procedure that will help us to systematically solve problems. This problem solving procedure will be used for the remainder of this course.

There are many processes that are carried out under isobaric and isochoric conditions and it is important to be familiar with them. In this lesson, you will learn how to analyze these special cases.

Cycles are an important part of this course. This lesson is only an introduction to power, refrigeration, and heat pump cycles. You will learn more about thermodynamic cycles in future chapters.
