4.1 Introduction
From the formal statement of the Second Law of
Thermodynamics, it is difficult to assign a physical
significance or a physical quality to entropy. (different from
internal energy, U)

6.1 Introduction
In this lecture, we examine the heat capacity as a function of temperature, compute the
enthalpy, entropy, and Gibbs free energy, as functions of temperature.
We then begin to assess phase eq

The second Law of
Thermodynamics
3.1 Introduction
The first law: U = q W
: Work and heat determine the change in U.
Is there a way to do maximum work during the change of state?
Answer: reversible or irreversible process

3.7 The Reversible Isothermal Compression of an Ideal Gas
When the compression is conducted isothermally (U=0), reversibly (S=0),
Thus, the work done on the gas = the heat withdrawn from the gas

The main power of the thermodynamic method stems from
its provision of criteria for equilibrium in materials systems
S and V are an inconvenient choice of independent
variables.

1) Calculate the entropy of 1 mole of Cu2S at 800 C and the entropy change when Cu2S is cooled
from 800 C to room temperature
So(Cu2S)=119.6 J/mol.K, CP= 81.6 J/mol.K
2) Calculate the standard entropy
