# Combined Gas Law

The Combined Gas Law is a fundamental principle in the field of thermodynamics, unifying Boyle's, Charles's, and Gay-Lussac's laws into a single equation. It describes the relationship between the pressure, volume, and temperature of a gas, emphasizing their interdependence when the quantity of gas remains constant. By mathematically representing these variables, the Combined Gas Law provides a comprehensive framework for understanding and predicting the behavior of gases under various conditions. This law plays a crucial role in diverse scientific disciplines, from chemistry and physics to engineering, facilitating the analysis and design of systems involving gases.
