astrowww.phys.uvic.ca

1 CHAPTER 7 THE FIRST AND SECOND LAWS OF THERMODYNAMICS 7.1 The First Law of Thermodynamics, and Internal Energy The First Law of thermodynamics is: The increase of the internal energy of a system is equal to the sum of the heat added to the system plus the work done on the system. In symbols: dU = dQ + dW.7.1.1 You may regard this, according to taste, …

Chapter 1: Basic Concepts of Thermodynamics

www.mhtl.uwaterloo.ca

First law of thermodynamics: one of the most fundamental laws of nature is the conservation of energy principle. It simply states that during an interaction, energy can change from one form to another but the total amount of energy remains constant. Second law of thermodynamics: energy has quality as well as quantity, and actual processes occur ...

The Three Laws of Thermodynamics - scott.k12.ky.us

www.scott.k12.ky.us

The Three Laws of Thermodynamics - The first law of thermodynamics, also called conservation of energy (energy can be neither created nor destroyed, it just changes form), states that the total amount of energy in the universe is constant. This means that all of the energy has to end up somewhere, either in the original form or in a different from.

The second law of thermodynamics deals with the natural direction of processes and the question of whether a given chemical reaction can occur by itself. The second law was formulated initially in terms of the efﬁciencies of heat engines, but it also leads to the deﬁnition of entropy, which is important
