Gay Lussac’s law - Class 11 PDF Download

Law of Combining Volume Gay Lussac established this law. According to this law, the volumes of reactants and products involved in gaseous reactions are related to each other by little integers, provided the volumes are measured at the adj temperature and pressure conditions. For example, in the reaction involving hydrogen and oxygen gases to give water vapour, it is create that two volumes of hydrogen combine with one volume of oxygen to give two volumes of water.





100 ml of hydrogen combine with 50 ml of oxygen to give 100 ml of noun vapour. Thus, the volumes of hydrogen and oxygen which combine together (i.e. 100 ml and 50 ml) bear a simple ratio of 2:1. Gay-Lussac's discovery of integer ratio in volume relationship is actually the law of definite proportions by volume. 



Propane tanks are extensively used in the kitchen. It’s not enjoyable, however, to discover you’ve verb out of gas halfway through a meal. On a hot day, gauges are used to measure the pressure inside gas tanks that read greater than on a cool day. When deciding whether or not to verb the tank before your next cookout, keep the gas temperature in mind. In this article, we’ll go over Gay Lussac’s Law in detail, including its formula and derivation.

What is Gay-Lussac’s Law?

Gay-Lussac’s law is a gas law which states that the pressure exerted by a gas (of a given mass and kept at a constant volume) varies directly with the absolute temperature of the gas. In other words, the pressure exerted by a gas is proportional to the temperature of the gas when the mass is fixed and the volume is constant.

This law was formulated by the French chemist Joseph Gay-Lussac in the year 1808. The mathematical expression of Gay-Lussac’s law can be written as follows:

P ∝ T ; P/T = k

Where:

  • P is the pressure exerted by the gas
  • T is the absolute tem

    Introduction: What Are the Gas Laws?

    The gas laws are a group of laws that govern the behaviour of gases by providing relationships between the following:

    • The volume occupied by the gas.
    • The pressure exerted by a gas on the walls of its container.
    • The absolute temperature of the gas.
    • The amount of gaseous substance (or) the number of moles of gas.

    The gas laws were developed towards the end of the 18th century by numerous scientists (after whom the individual laws are named). The five gas laws are listed below:

    • Boyle’s Law: It provides a relationship between the pressure and the volume of a gas.
    • Charles’s Law: It provides a relationship between the volume occupied by a gas and the absolute temperature.
    • Gay-Lussac’s Law: It provides a relationship between the pressure exerted by a gas on the walls of its container and the absolute temperature associated with the gas.
    • Avogadro’s Law: It provides a relationship between the volume occupied by a gas and the amount of gaseous s
