Ideal Gases

• Unified atomic mass units - approximately equal to the number of nucleons
• Mole - SI base unit of an amount of substance. It is the amount containing as many particles as there are atoms in 12g or carbon -12
• Avogadro Constant - the number of units in one mole of any substance ( molecular weight in grams)
• Molar mass - mass in grams in one mole
• Boyle's law - the pressure exerted by a fixed mass of gas is inversely proportional to its volume, provided the temperature of the gas remains constant
• Charles' Law - the volume occupied by a gas at a constant pressure is directly proportional to its thermodynamic temperature
• Boltzmann Constant - a constant relating the average kinetic energy of the particles in a gas, to the gas' temperature
• Ideal gas - a gas that obeys the equation of state pV=nRT at all pressures, volumes and temperatures
• Pressure law - as temperature increases the pressure of a gas of constant volume increases
• Kinetic Theory of gases - a theory that links the microscopic properties of particles to the macroscopic properties of gases
