Which of the following properties does not give evidence of the kinetic theory of matter?

Step 1: Analyze the question We need the property that does NOT support the kinetic theory of matter.

Step 2: Concept The kinetic theory says matter is made of tiny particles that are in constant random motion. The particles' energy and the forces between them determine whether the matter is a solid, liquid or gas.

Evidence for the theory includes:

• Diffusion: particles move randomly and spread from high to low concentration (e.g. the smell of cooking rice spreading through a house).
• Melting: heating gives particles more kinetic energy, so they overcome the forces holding them in fixed positions.
• Evaporation: faster-moving surface particles escape from the liquid.
• Others include Brownian motion, gas pressure and the expansion of gases.

Step 3: Examine each option

• A. Diffusion: direct evidence of particle motion, so it supports the theory.
• B. Melting: shows particles gaining energy and changing arrangement, so it supports the theory.
• C. Polymerization: this is a chemical reaction in which small monomer molecules join by covalent bonds to form long chains. It is about bonding and chemical change, not the physical motion and energy of particles, so it does not give evidence of the kinetic theory.
• D. Evaporation: particles escape from the liquid surface, so it supports the theory.

Step 4: Answer The correct option is C. Polymerization.

Tip: Kinetic theory questions are about physical changes and particle movement (diffusion, Brownian motion, melting, boiling, evaporation). If an option describes a chemical reaction that makes new substances, such as polymerization, it is usually the odd one out.
