  • In all Charles's and Pressure Law calculations, temperature must be converted to Kelvin: T(K) = t(°C) + 273.
  • Absolute Zero (-273.15°C or 0 K) is the temperature at which ideal gas volume and pressure theoretically equal zero.
  • The volume expansion coefficient (αv) and pressure coefficient (βp) for all ideal gases equal 1/273 °C-1.
  • Boyle's law assumes constant temperature, Charles's law assumes constant pressure, Gay-Lussac assumes constant volume.
  • The Universal Gas Constant R = 8.314 J/(mol.K).
