Conduction is the transfer of heat energy that occurs between two objects that are touching. Thus, conduction occurs between the particles of solids, liquids, and gases that collide into one another.

During conduction, heat will always transfer from the hotter to the colder object. Temperature is a reflection of the average kinetic energy of the particles of a substance. During conduction, the warmer and faster particles collide into cooler and slower particles. When this occurs, energy is moved from the warmer particles that have more energy to the cooler particles that have less energy. This process continues until the system has reached equilibrium and both objects are the same temperature.

Because the particles of solids are closest to one another and can easily bump into one another, conduction occurs the fastest in solids. Similarly, because the particles of gases are the farthest from one another, conduction is the slowest in solids.
