Brownian Motion Simple Definition:
The continuous random motion of the particles of microscopic size suspended in air or any liquid is called Brownian motion.
We are giving a detailed and clear sheet on all Physics Notes that are very useful to understand the Basic Physics Concepts.
What is Brownian Motion in Physics? | Definition, Examples – Kinetic Theory of Gases
Brownian motion is observed with many kind of small particles suspended in both liquids and gases.
Brownian motion is due to the unequal bombardment of the suspended particles by the molecules of the surrounding medium.
Brownian Motion Examples
- The motion of pollen grains on still water.
- Movement of dust motes in a room (although largely affected by air currents)
- Diffusion of pollutants in the air.
- Diffusion of calcium through bones.
Kinetic Theory of Gases:
In this concept, it is assumed that the molecules of gas are very minute with respect to their distances from each other. The molecules in gases are in constant, random motion and frequently collide with each other and with the walls of any container.
In this portion, you will learn about the properties of gases, based on density, pressure, temperature and energy. Continue reading here to learn more.
