Web29 apr. 2013 · Professor Susskind derives the formula for the pressure of an ideal gas. He begins by introducing the Helmholtz free energy, and the concept of adiabatic processes. These concepts lead to the definition of pressure as the change of energy with volume at a fixed entropy, and then to the famous equation of state for an ideal gas: pV = NkT. Web1.2 Counting States We often specify certain macroscopic properties, then count microstates consistent with those properties. For instance, we try to count microstates within a certain energy gap, say, between Eand E+ E.
