Pressure temperature law gay lussac biography

Relationship between pressure and temperature of a gas at constant volume

Gay-Lussac's law usually refers to Joseph-Louis Gay-Lussac's law of combining volumes of gases, discovered in 1808 and published in 1809.^[1] However, it sometimes refers to the proportionality of the volume of a gas to its absolute temperature at constant pressure.

The latter law was published by Gay-Lussac in 1802,^[2] but in the article in which he described his work, he cited earlier unpublished work from the 1780s by Jacques Charles. Consequently, the volume-temperature proportionality is usually known as Charles's Law.

Law of combining volumes

The law of combining volumes states that when gases chemically react together, they do so in amounts by volume which bear small whole-number ratios (the volumes calculated at the same temperature and pressure).

The ratio between the volumes of the reactant gases and the gaseous products can be expressed in simple w 11.11: Gay-Lussac's Law- Temperature and Pressure DYMI
