In 1808, the French chemist Joseph Louis Gay-Lussac reported the results of new experiments together with a generalization known today as Gay-Lussac’s law of combining gases.
Gay-Lussac’s Law is applicable only to gases. The volumes of liquids or solids involved in the reactants or products are not governed by Gay Lussac’s law.
Gay Lussac Law Formula Solved Examples
Some of the solved problems based on Gay Lussac Law Formula are given below.
Question 1: What is the volume of a quantity of a gas at 27oC if its volume was 400mL at 0oC? The pressure remains constant.
Since the temperature increased, the volume increased. Here we must use a temperature factor greater than 1, that is 300/273
Question 2: Solve Gay-Lussac’s Law to get an expression for the unknown volume. Substitute the appropriate data into the formula.
