REFLECTION
Are you comfortable with the terms mole and Avogadroâs number? Do you know the assumptions behind the kinetic model of an ideal gas? Do you understand the origin of pressure in a gas? Can you solve problems using the gas laws? Do you understand the connection between kelvin temperature and average random kinetic energy? Do you understand the conditions under which a real gas behaves as an ideal gas?
