What is conduction in terms of heat transfer?

Conduction refers specifically to the transfer of heat between molecules through direct contact. In this process, heat energy is passed from one molecule to another as they collide. When two objects at different temperatures come into contact, energy will flow from the hotter object to the cooler one until thermal equilibrium is reached. This method of heat transfer is essential in various physiological processes, including temperature regulation in the body, where heat from deeper tissues is conducted to the skin surface. This direct interaction between particles allows for efficient heat transfer in solid materials, making conduction a fundamental concept in understanding how temperatures change in biological systems and in various environmental contexts.
