Absolute Temperature A temperature value relative to absolute zero. Absolute Zero The lowest possible temperature of a system, where no heat remains and the particles in the system have no kinetic energy. Avogadro Constant The number of particles that make up one mole of any gas. Boltzmann Constant A constant relating the average kinetic energy of the particles in a gas, to the gas’ temperature. Boyle’s Law The pressure of an ideal gas is inversely proportional to its volume when ...

Chem 219: Exam 3 Questions With 100% Correct Answers Avogadro's Law equal volumes of gases at the same temperature and pressure contain equal numbers of molecules Boyle's Law Boyle's Law states that at constant temperature and moles, pressure and volume are inversely proportional. Mathematically this is written as: PV = PV Charles' Law the law that states that for a fixed amount of gas at a constant pressure, the volume of the gas increases as the temperature of the gas increases ...
