What is the transfer of energy through particles that are in direct contact?

Answer 1

The transfer of energy through particles that are in direct contact is known as conduction. This process occurs primarily in solids, where neighboring particles (atoms or molecules) collide with one another, transferring kinetic energy from the hotter (higher-energy) particles to the cooler (lower-energy) ones. This energy transfer continues until thermal equilibrium is reached, meaning that the temperature throughout the materials becomes uniform. Conduction is an important process in various applications, such as heating, cooling, and thermal insulation.
