Brownian motion is the random movement of molecules suspended in a liquid or a gas. What type of energy makes these molecules move?
A) chemical energy
B) kinetic energy
C) potential energy
D) conversion of energy

Question

Quizplus · Accepted Answer

Brownian motion is a result of the kinetic energy of the molecules, which causes them to move randomly. The other choices (chemical energy, potential energy, conversion of energy) are not directly related to the motion of the molecules in Brownian motion.
