Chapter 2 Classical Thermodynamics: The Second Law 2.1 Heat
... This is a substantial chapter, containing many important results and many techniques. There are two common technical difficulties for many students at the beginning: proof of theorems and partial derivatives. We will emphasize the understanding and applications of the theorems and we will do many pr ...

... Homogeneous system: A system is said to be “homogeneous” if it consists of only one phase and uniform thought. Ex. a solution of sugar in water. Heterogeneous system: When a system consists of two or more phases and is not uniform throughout it is called heterogeneous. Ex .Ice in water, chloroform i ...

heat engine
... A heat engine is any device that uses heat to perform work. It has three essential features. 1. Heat is supplied to the engine at a relatively high temperature from a place called the hot reservoir. 2. Part of the input heat is used to perform work by the working substance of the engine. 3. The rema ...

... We need to generalize the definition of entropy since real systems are typically spontaneous and irreversible, moving from a state of non-equilibrium to a state of equilibrium. Second law can be formulated as 4 postulates: 1. There exists a STATE VARIABLE for any substance called the ENTROPY. 2. Ent ...

On Clausius, Boltzmann and Shannon Notions of Entropy
... Such meaning was inspired by an earlier formulation made by the French physician and mathematician Sasi Carnot (see [4]) who was known his broader formulation of the Second Law of Thermodynamics: entropy represents the energy no longer capable to perform work. In isolated systems it can only grow. S ...
