Question

(a) diffusion.
(6) Brownian motion.
Name the scientist who studied the movement of pollen grains suspended in water through a microscope.
What is this phenomenon known as ?​

Answer 1

Answer:

Diffusion- Diffusion is the movement of a substance from an area of high concentration to an area of low concentration...

Brownian Motion- The random movement of microscopic particles suspended in a liquid or gas, caused by collisions between these particles and the molecules of the liquid or gas.....

And The scientist named “Robert Brown” proposed a phenomenon named “Brownian motion or Brownian movement” which explains the pollen grains’ movement when it is suspended in water particles caused by the bombardment with the surrounding medium. He was the one who first observed the irregular motion of the particles through the microscope in the year 1827. This invention creates a huge impact on the “kinetic theory of molecules”....

Hope it helps u...

Answer 2

Answers ROBERT BROWN ISTHE SCIENTIST WHO STUDIED THE MOVEMENT OF POLLEN GRAINS SUSPENDED IN WATER.

♤THIS PHENOMENA IS KNOWN AS BROWNIAN MOTION.

BROWNIAN MOTION:THIS IS THE ERRATIC MOTION OF PARTICLES IN FLUID DUE TO THE COLLISION WITH EACH OTHER.

●HERE THE PARTICLES ARE POLLEN GRAINS.
