What is Transmission of Heat ?
The transfer of thermal energy from higher to lower temperature zones is referred to as heat transmission. Conduction occurs through direct contact between objects, while convection relies on the movement of fluids. Radiation involves the emission and absorption of electromagnetic waves. Efficient insulation materials reduce heat transfer. Understanding heat transmission is vital for optimizing energy efficiency, designing thermal management systems, and analyzing heat distribution in various applications. It plays a crucial role in fields such as engineering, architecture, climate science, and materials science.
