Brownian movement
Brownian movement, also known as Brownian motion, is the random motion of microscopic particles suspended in a fluid (liquid or gas). It was first observed by the botanist Robert Brown in 1827 and later explained by Albert Einstein in 1905.
Brownian movement occurs due to the continuous collision of the fluid molecules with the suspended particles. The particles are constantly bombarded by the fast-moving fluid molecules, causing them to move in a zigzag pattern. The motion is random and unpredictable, as the particles are influenced by the cumulative effect of countless collisions from all directions.
The key factors affecting Brownian movement include the size of the particles and the temperature of the fluid. Smaller particles experience more significant Brownian motion because they are more strongly affected by collisions with fluid molecules. Additionally, higher temperatures increase the kinetic energy of the fluid molecules, leading to more vigorous particle motion.
Brownian motion has important applications in various fields, including physics, chemistry, biology, and medicine. It provides evidence for the existence of atoms and molecules, as the random motion of particles is attributed to the individual collisions with these tiny particles. Brownian motion is also utilized in techniques such as Brownian dynamics simulations and particle tracking to study and analyze systems at the microscopic level.
The AIIMS Chemistry syllabus covers various topics, including Brownian movement. Brownian movement refers to the random motion of microscopic particles suspended in a fluid due to collisions with the fluid molecules. It is caused by the thermal energy of the fluid molecules. The key concepts related to Brownian movement that may be covered in the syllabus include:
