**Introduction (Chaps. 1 & 2)**

- Scope of Thermodynamics. What's ahead (Overview).
- Quasistatic Processes. Walls: adiabatic
*vs.*diathermic, resistive*vs.*conductive. - Equations of state. Extensive and intensive parameters. Equations of state of an ideal gas. Kinetic temperature. Notion of a fundamental equation.
- Mathematical background
- Exact (perfect, or complete) differentials, e.g.,
*dU, dV*. Incomplete (imperfect) differentials:*dQ, dW*. - Volume susceptibilities: compressibility and the expansion coefficient. Maxwell-type thermodynamic identities. Problem 1 and solution.

**First and Second Laws (Chaps. 3 and 4)**- Internal energy, heat and work. Isotherm and adiabat (isentrope). Configuration
(pressure) work,
*dW=-pdV*. - Conservation of energy in thermodynamics: The First Law. Some consequences of the First Law. Problem 2 and solution.
