This gives rise to the molar volume of a gas, which at STP Avogadro constant Boltzmann constant Gas constant. This hypothesis meant that the previously stated result. By using this site, you agree to the Terms of Use and Privacy Policy. This page was last edited on 21 Januaryat

Temperature must be in Kelvin for the equation to work.

## Gay-Lussac's law

For example, Gay-Lussac found that 2 volumes of hydrogen and 1 volume of oxygen would react to form 2 volumes of gaseous water. Ideal Gas Law Quiz Gases: The Gas Laws I: Gases behave in a similar way over a wide variety of conditions because they all have molecules which are widely spaced, and the equation of state for an ideal gas is derived from kinetic theory.

Based on Gay-Lussac's results, Amedeo Avogadro theorized that, at the same temperature and pressure, equal volumes of gas contain equal numbers of molecules Avogadro's law.

A graph of pressure vs. Gay-Lussac's Law shows the relationship between the Temperature and Pressure of a gas. With the addition of Avogadro's lawthe combined gas law develops into the ideal gas law:. For example, Gay-Lussac found that 2 volumes of hydrogen and 1 volume of oxygen would react to form 2 volumes of gaseous water. Gay-Lussac's law can refer to several discoveries made by French chemist Joseph Louis Gay-Lussac — and other scientists in the late 18th and early 19th centuries pertaining to thermal expansion of gases and the relationship between temperature, volume, and pressure.
