Molecules are in a state of continuous_________

Answer 1

• A molecule is defined as the smallest unit of matter, which has an independent existence and can retain the complete physical and chemical properties of matter.
• According to the kinetic theory of gases, Molecules are in a state of continuous motion and do not stop for any length of time.
• It is on account of this continuous motion, thus molecules possess kinetic energy.

Therefore, molecules are in a state of continuous motion.
