1. Fredric Brown
2. Robert Brown
3. Emmett Brown

Q.

The Brownian motion is due to:?

Q.

Name the factors on which the intensity of Brownian motion depends.

Q.

The zig-zag random movement of particles of colloidal solution is called _________.

Q. In which medium does colloidal particles exhibit brownian motion?

1. Only solids
2. Only liquids
3. Only gases
4. Only fluids

Q. Colloidal particles dispersed in a liquid medium undergo a random, zigzag motion called the Brownian movement. The reason for this phenomenon is:

1. Extensive and uniform solvation
2. Unbalanced forces caused by the bombardment of atoms of dispersion medium that surround the dispersed phase particles
3. None of the above
4. Surface tension

1. Only solids
2. Only liquids
3. Only gases
4. Only fluids

1. scattering of light
2. absorption of light
3. random motion
4. straightline motion

Q.

Define Brownian motion.
