The Kinetic Theory of Gases

The Kinetic Theory of Gases explains that gases are made up of tiny particles called molecules or atoms that are in constant, rapid motion. These particles move in all directions, colliding with each other and the walls of their container. The pressure of a gas results from these collisions, while temperature reflects how fast the particles are moving—faster molecules mean higher temperature. This theory helps us understand gas behavior, like expansion, compression, and how temperature relates to energy at the microscopic level, providing a foundation for many scientific and engineering applications.
