## Gay Lussac Law Formula

The kitchen makes significant use of propane tanks. But finding out midway through a meal that you’ve run out of gas is not fun. The pressure within gas tanks is measured using gauges, which read higher on hot days than they do on cool ones. The air temperature should be taken into consideration while deciding whether or not to refill the tank prior to your next barbeque. The Gay Lusaac Law Formula and its derivation have been covered in-depth by Extramarks experts in the article that is posted on the Extramarks website and mobile application.

A gas law known as the Gay Lusaac Law Formula asserts that a gas’s pressure (when kept at a constant volume and mass) varies directly with its absolute temperature. In other words, while the mass is fixed and the volume is constant, the pressure a gas exerts is proportional to the temperature of the gas.

In the year 1808, French scientist Joseph Gay-Lussac created this law. Gay Lusaac Law Formula can be expressed mathematically as follows:

P ∝ T ; P/T = k

Where:

• P is the pressure that the gas is applying.
• T is the gas’s actual temperature, and k is a fixed value.

Gay Lusaac Law Formula states that, when the volume is held constant, the pressure of a given amount of gas varies directly with the absolute temperature of the gas. Gay Lusaac Law Formula can be expressed mathematically as P/T=k. It falls within the category of the ideal gas law.

Boyle’s law, Charles’ law, and Avogadro’s law are the other three ideal gas laws, and they each have their own articles and pdfs on Extramarks’ website. The study of homosexual lussac’s law is the primary focus of this essay.

Temperature, volume, and pressure are the three factors that aid in the study of gases. Boyle’s law’s temperature, Charles law’s pressure, and Gay Lusaac Law Formula are all kept constant while being studied.

### Solved Examples

The propane tanks used for barbecue grills are an illustration of the Gay Lusaac Law Formula. People use gauges that measure the pressure in the tank to keep an eye on how much gas is still in it and to keep track of how much is left. When the air is heated, the pressure gauge reads a greater value. Therefore, before adding more propane to the tank, the air temperature must be considered.

The French scientist who discovered the connection between a gas’s pressure and absolute temperature is honored with the term “Gay Lusaac Law Formula.” His name was Joseph Gay Lussac (1778-1850).
