Equation of state
15.2What the syllabus asks of you
- understand that a gas obeying pV ∝ T, where T is the thermodynamic temperature, is known as an ideal gas
- recall and use the equation of state for an ideal gas expressed as pV = nRT, where n = amount of substance (number of moles) and as pV = NkT, where N = number of molecules
- recall that the Boltzmann constant k is given by k = R / NA
