9. Behaviour of Perfect Gas and Kinetic Theory

Gases are characterized by their lack of fixed shape and volume, making them easily compressible. The behavior of gases can be explained using the Kinetic Theory, which describes gas particles as constantly moving and colliding elastically. Important gas laws like Boyle's, Charles's, and Gay-Lussac's help predict gas behavior under various conditions, connecting with applications in real-world scenarios like scuba diving and hot air balloons.
