Match can conduct heat more easily because of large numbers of

Options

A. free protons
B. free electrons
C. free neutrons
D. all of these

Explanation

**Step-by-Step Solution:**

1. **Understanding Heat Conduction**: Heat conduction is the process by which heat energy is transferred through a material without the movement of the material itself. This process is largely dependent on the presence of free-moving charged particles within the material.

2. **Identifying the Material**: In the case of a matchstick, the head of the match contains a mixture of chemicals, including an oxidizing agent and a combustible material. The presence of these materials allows for the ignition and subsequent heat production when the match is struck.

3. **Role of Electrons**: The key to understanding why matches can conduct heat easily lies in the presence of free electrons. Free electrons are electrons that are not bound to any particular atom and can move freely throughout the material. This mobility allows them to transfer energy (heat) quickly.

4. **Comparison of Particles**: Among protons, electrons, and neutrons, electrons are the particles that are most responsible for heat conduction in conductive materials. Protons and neutrons are found in the nucleus of an atom and do not contribute to heat conduction in the same way.

5. **Conclusion**: Therefore, the reason matches can conduct heat easily is due to the large number of free electrons present in the materials that make up the matchstick.

**Final Answer**: The correct match is "Electron" as the particle responsible for the efficient conduction of heat in matches.
