Ideal gases

What you'll learn

• Understand that amount of substance is an SI base quantity with the base unit mol
• Use molar quantities where one mole of any substance is the amount containing a number of particles of that substance equal to the Avogadro constant NA
• 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 and as pV = NkT
• Recall that the Boltzmann constant k is given by k = R/NA
• State the basic assumptions of the kinetic theory of gases
• Explain how molecular movement causes the pressure exerted by a gas and derive and use the relationship pV = 1/3 Nm<c2>
• Deduce that the average translational kinetic energy of a molecule is 3/2 kT
