Which of the following phenomena is the practical evidence for the existence of the continual motion of molecules
Transitional Motion
Rotational Motion
Brownian Motion
Oscillatory Motion
Correct answer is C
Brownian motion, also called Brownian movement, any of various physical phenomena in which some quantity is constantly undergoing small, random fluctuations.
If a number of particles subject to Brownian motion are present in a given medium and there is no preferred direction for the random oscillations, then over a period of time the particles will tend to be spread evenly throughout the medium.
