The law that explains the relationship between pressure and volume in gases is Boyle's Law. This fundamental principle states that, at a constant temperature, the volume of a gas is inversely proportional to its pressure. In other words, if the volume of a gas decreases, the pressure increases, provided the temperature remains unchanged. This relationship can be mathematically expressed as \( P \times V = k \), where \( P \) is the pressure, \( V \) is the volume, and \( k \) is a constant for a given amount of gas.

Understanding Boyle's Law is crucial for applications in various fields, including chemistry, physics, and engineering, as it helps in predicting how gases will behave under different pressure and volume conditions in real-world scenarios.
