Mariotte's Law, also known as Boyle's Law, states that at a constant temperature, the volume of a gas is inversely proportional to its pressure. However, there are several synonyms for this law, including the pressure-volume law, Boyle-Mariotte Law, and Boyle's-Mariotte Law. This law is named after two scientists, Robert Boyle and Edme Mariotte, who independently discovered it. They both showed that the volume of a gas decreases as the pressure increases, and vice versa. This law has important applications in various fields such as engineering, physics, and chemistry. The study of this law can help in understanding the behavior of gases and the relationship between their pressure and volume.
