The Brownian Motion of very small particles suspended in a gas is caused by:
A. Collisions between the particles and gas molecules
B. Attraction between atoms of the same kind
C. The influence of Earths gravitational field
D. Repulsion between protons and electrons
E. The influence of Earths magnetic field
Homework Answers
Brownian motion is defined as the irregular motion of small particles suspended in a liquid or a gas, caused by the bombardment of the particles by molecules of the medium .
In the question , the medium is gas .So, the Brownian motion will be caused by collision of small particles with gas molecules.
Hence , correct option is A
