By the end of this unit a successful student should be able to:
- Heat Transfer & Thermal Expansion (2% of the AP Test)

- Thermodynamics & the Ideal Gas Law (7% of the AP Test)
- Describe the Zeroth Law of Thermodynamics and apply it to problems (13-3)
- Describe the kinetic theory of gasses and relate kinetic energy to the temperature of a gas, and momenta of gas particles to pressure. (13-10)
- Solve problems relating pressure, volume, density, temperature and amount for ideal gasses using the Ideal Gas Law. Describe the experiments which led to the development of the gas laws. (13-6 13-9)
- First law & PV diagrams. Relate temperature to Uint. Describe isothermic, isobaric, isovolumetric and adiabatic changes and relate them to the First law & PV diagrams. (14-2, 15-1, 15-2)
- 2nd law & heat engines. Describe a Carnot engine, Carnot cycle and heat-engine efficiency. Define entropy. (15-4, 15-5)

- Thermodynamics is the study of the affects of internal energy on a system. This includes the study of temperature and of entropy. Entropy is a measure of the disorder in a system. A system with low entropy might have all of its components near one particular energy state. A system with high entropy would have its components in a wide distribution of energy states. A neatly organized room is in a state of low entropy. A desk whose contents are distributed haphazardly about it, with only a few items in their assigned places (socks in a sock drawer for example), would be in a state of high entropy. Modern thermodynamics is highly dependent on mathematical tools from statistics.

- Following Boyle's Law, the Law of Charles & Gay-Lussac, The Ideal Gas Law (PV=nRT)is most students' introduction to topic of thermodynamics. this Java-based Gas Law Program by Kirk Haines, John Gelder, and Michael Abraham presents a cross-sectional view of piston enclosing a particle model of an ideal gas model of a helium, neon mixture. The user is able to vary the pressure, temperature, volume, and number densities and watch how the other quantities change, and how the speed distribution of the particles varies.
- The Maxwellian Demon site contains a number of articles and links relating to thermodynamics and its relation to information theory.
