One of the basic assumptions of thermodynamics is the idea that we can arbitrarily divide the universe into a system and its surroundings.The boundary between the system and its surroundings can be as real as the walls of a beaker that separates a solution from the rest of the universe (as in the figure below).

For more than a century and a half of physics, the Second Law of Thermodynamics, which states that entropy. which says that if you open a door between two rooms, one hot and one cold, they will.

We will now present the first law of thermodynamics. As usual, we start with the expression for closed systems, well known to all, and we generalize for open.

That’s a pretty good question, but in order to answer it we have to clarify precisely what it is physics says about the first law of thermodynamics. The first thing we have to do is determine what a "closed system" is. When we look at a physical situation and draw an imaginary circle around it, we.

– [Voiceover] Let’s now explore the first law of thermodynamics. And before even talking about the first law of thermodynamics, some of you might be saying, "Well, what are thermodynamics?" And you could tell from the roots of this word. You have thermo, related to thermal, it’s dealing with.

Introduction. A description of any thermodynamic system employs the four laws of thermodynamics that form an axiomatic basis. The first law specifies that energy can be exchanged between physical systems as heat and work. The second law defines the existence of a quantity called entropy, that describes the direction, thermodynamically, that a system can evolve and quantifies the state of order.
