The law of Gay – Lussac is a variant of the ideal gas law where the volume of gas is held constant. The pressure of a gas is directly proportional to its temperature while the volume is kept constant. P / T = constant or Pi / Ti = Pf / Tf are the standard calculations for Gay – Lussac ‘s law.

Some real-life examples of Gay – Lussac’s law are the rupture of a pressure cooker, an aerosol can, and a tyre. All these substances explode when expose to higher temperatures. Gay – Lussac’s law is the law that says the pressure of gas increases with its temperature, or vice versa.

It states that when gases combine or are produced in a chemical reaction they do so in a simple ratio by volume , provided all gases are at the same temperature and pressure.

Boyle’s Law is the relationship between the pressure and volume of the gas system when the temperature remains constant. The final relationship that we will discuss the Gay – Lussac’s Law , which gives us a relationship between pressure and temperature when the volume remains constant.

Gas Laws : Boyle’s Law , Charle’s Law , Gay-Lussac’s Law , Avogadro’s Law .

The formula created by Charles was V _{1} /T _{1} = V_{2}/T_{2}. We can also further consider this to give V _{1} /T _{1} = V_{2}/T_{2} = V_{3}/T_{3} = V_{4}/T_{4}. Charles Law in General Gas Equation: The combined gas laws describing the properties of gases relating to pressure, temperature and volume give the General Gas Equation.

The gas laws consist of three primary laws : Charles’ Law , Boyle’s Law and Avogadro’s Law (all of which will later combine into the General Gas Equation and Ideal Gas Law ).

The Gas Laws: Pressure Volume Temperature Relationships Boyle’s Law : The Pressure-Volume Law . Charles’ Law : The Temperature-Volume Law. Gay-Lussac’s Law: The Pressure Temperature Law. The Combined Gas Law .

The ideal gas law ( PV = nRT ) relates the macroscopic properties of ideal gases.

Avogadro’s law , a statement that under the same conditions of temperature and pressure, equal volumes of different gases contain an equal number of molecules.

In the equation PV = nRT , the term “ R ” stands for the universal gas constant. The universal gas constant is a constant of proportionality that relates the energy of a sample of gas to the temperature and molarity of the gas. It is sometimes called the ideal gas constant, the molar gas constant.

The law itself can be stated as follows: For a fixed mass of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional. Or Boyle’s law is a gas law , stating that the pressure and volume of a gas have an inverse relationship.

The ideal gas law is: pV = nRT, where n is the number of moles, and R is universal gas constant. The value of R depends on the units involved, but is usually stated with S.I. units as: R = 8.314 J/mol·K.
