Kinetic Theory of Gases: Molecular Motion, Pressure, and Speed Distribution
This PowerPoint explores the Kinetic Theory of Gases, explaining the behavior of gas molecules in motion. It begins with Bernoulli’s work, using the concept of rapidly moving molecules to explain pressure. The presentation discusses one-dimensional and multi-dimensional gas systems, illustrating how molecules collide with the walls of a container, transferring momentum and creating pressure. The concept of molecular speed and the ideal gas law (PV = nRT) are introduced, relating pressure, volume, and temperature to molecular motion. Maxwell′s speed distribution is also covered, detailing how molecules have varying speeds and the probability of finding a molecule with a particular energy. Additionally, the mean free path is discussed, describing how gas molecules travel between collisions.
