In order for conduction to occur, particles must make physical contact with each other. Conduction is the transfer of heat or electricity through a substance or between objects that are in direct contact with each other. When particles come into contact, they transfer energy through collisions, leading to the flow of heat or electricity. This transfer of energy continues until a thermal equilibrium is reached, meaning the particles reach the same temperature or electrical potential. So, for conduction to happen, it is essential for the particles to make physical contact and exchange energy.
