Question

2. Tick the most appropriate answer:

(vi) Molecules are in a state of continuous motion, so they possess :

• A. potential energy
• B. kinetic energy
• C. mechanical energy
• D. either (a) or (b)

Answer 1

The correct option is B

kinetic energy

• A molecule is defined as the 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.
• Due to the continuous motion, molecules possess kinetic energy.
• Therefore, molecules are in a state of continuous motion.

Hence, the correct answer is an option (B).
