Conduction occurs fastest in solids due to the close proximity and strong interactions between their particles. In solids, particles are tightly packed and can transfer kinetic energy very efficiently through direct contact. When one particle is heated, it vibrates more vigorously and transfers this energy to its neighboring particles, resulting in rapid energy transfer throughout the material.

In contrast, in liquids and gases, the particles are farther apart, which limits the efficiency of energy transfer. In liquids, while conduction can still occur, there is more space between particles, meaning that energy may take longer to pass from one particle to another. In gases, the particles are much more loosely arranged and move freely, which significantly hinders conduction as the energy transfer relies on collisions that occur far less frequently than in solids.

Plasmas, while capable of conducting electricity due to their ionized state, do not excel in thermal conduction relative to solids because the amount of energy transfer between charged particles is not as efficient as it is in the tightly packed structure of solids. This makes solids the state of matter in which conduction occurs most rapidly.
