Kinetic Molecular Theory of Gases

Najam Academy・6 minutes read

The Kinetic molecular theory of gases explains gas behavior through postulates such as tiny, identical particles in random motion undergoing elastic collisions with negligible volume. Additionally, it clarifies the relationship between gas pressure, volume, and temperature, as well as the inflation of a balloon by gas molecules exerting pressure on its inner surface.

Insights

  • Gas behavior, such as pressure, volume, and temperature relationships, can be understood through the Kinetic Molecular Theory, which posits that gas molecules are tiny, identical particles that move randomly and undergo elastic collisions.
  • The inflation of a balloon is explained by gas molecules exerting pressure on its inner surface, showcasing how the theory elucidates real-world phenomena and the fundamental principles governing gas behavior.
