The online gas simulations on this page will help you to better understand how gases behave and which are the main laws that help us to understand that behavior.
Gases are a state of matter characterized by their ability to expand and occupy all the available space in a container. There are different laws that govern their behavior, among which the laws of Boyle-Mariotte, Charles, Gay-Lussac and the ideal gas law stand out.
The Boyle-Mariotte law states that, at constant temperature, the volume of a gas is inversely proportional to its pressure. That is, if the pressure increases, the volume decreases, and vice versa.
Charles’ law states that, at constant pressure, the volume of a gas is directly proportional to its absolute temperature. This means that if the temperature of a gas is increased, its volume will also increase.
Gay-Lussac’s law states that, at constant volume, the pressure of a gas is directly proportional to its absolute temperature. That is, if the temperature of a gas is increased, its pressure will also increase.
The ideal gas law states that the product of the pressure and volume of a gas is proportional to the amount of substance, the temperature and a universal gas constant.
In addition to these laws, there are others that explain the behavior of gases, such as Dalton’s law of partial pressures and Avogadro’s law of molar volume. The study of gases and their laws is fundamental in different areas of science and technology, such as chemistry, physics, engineering and medicine.
Kinetic theory of gases
The kinetic theory of gases is a model that describes the behavior of gases at the microscopic level. It explains their macroscopic properties, such as pressure, temperature and volume, from the motion and collisions of their molecules. Observe what happens in this simulation by increasing the agitation of the molecules and increasing their collisions.
Introduction and gas laws
Pump gas molecules into a box and discover what happens as you change the volume, add or remove heat, etc.

Boyle-Mariotte’s Law
This simulation shows the application of Boyle-Mariotte’s law. Change the pressure applied to the gas and observe how its volume changes.
Charles’ Law
This simulation shows the application of Charles’ law. Change the temperature applied to the gas by moving it to the left and right and observe how its volume changes.
