Frequently Asked Questions
What is the Statement of the Law of Definite Proportions? The law of definite proportions, also known as the law of constant proportions, states that the individual elements that constitute a chemical compound are always present in a fixed ratio (in terms of their mass). This ratio does not depend on the source of the…

What are the Exceptions
Despite being a building block in the development of chemistry, the law of constant proportions does not hold true for all chemical compounds. Some exceptions to this law are listed below. Some non-stoichiometric compounds have varying compositions of elements between samples. These compounds obey the law of multiple proportions instead. One such example is wustite,…

Law Of Constant Proportions
What is the Law of Constant Proportions? The law of constant proportions states that chemical compounds are made up of elements that are present in a fixed ratio by mass. This implies that any pure sample of a compound, no matter the source, will always consist of the same elements that are present in the…

Frequently Asked Questions
How does Boyle’s law work? Boyle’s law is a gas law that states that a gas’s pressure and volume are inversely proportional. When the temperature is kept constant, as volume increases, pressure falls and vice versa. Why is Boyle law important? Boyle’s law is significant because it explains how gases behave. It proves beyond a…

Solved Exercises on Boyle’s Law
Exercise 1 A fixed amount of a gas occupies a volume of 1L and exerts a pressure of 400 kPa on the walls of its container. What would be the pressure exerted by the gas if it is completely transferred into a new container having a volume of 3 liters (assuming the temperature and quantity…

Examples of Boyle’s Law
When a filled balloon is squeezed, the volume occupied by the air inside the balloon decreases. This is accompanied by an increase in the pressure exerted by the air on the balloon, as a consequence of Boyle’s law. As the balloon is squeezed further, the increasing pressure eventually pops it. An illustration describing the increase…

Formula and Derivation
As per Boyle’s law, any change in the volume occupied by a gas (at constant quantity and temperature) will result in a change in the pressure exerted by it. In other words, the product of the initial pressure and the initial volume of a gas is equal to the product of its final pressure and…

Boyle`s Law
What is Boyle’s Law? Boyle’s law is a gas law which states that the pressure exerted by a gas (of a given mass, kept at a constant temperature) is inversely proportional to the volume occupied by it. In other words, the pressure and volume of a gas are inversely proportional to each other as long…
