Each problem is worth 10 points. Ch. 3 Overview of Classical Thermodynamics 1. Problem 3.1, ( P,T ). Among the questions asked in this problem, calculate the isothermal compressibility. To solve this problem, just follow the definitions given in the chapter. 2. Problem 3.2, Maxwell identities. To solve this problem, just follow the definitions given in the chapter. 3. The entropy change in mixing of two gases. Consider two different gases separated by a wall, as shown in Fig. 3.2. One gas has N 1 particles and occupies the volume V 1 , and another gas has N 2 particles and occupies the volume V 2 . The gases are in thermal equilibrium with each other, so their temperatures are equal....
