Heat transfer theory

Heat transfer theory explains how thermal energy moves from warmer areas to cooler ones. It occurs mainly through three processes: conduction (direct contact transfers energy between objects), convection (fluid movement carries heat), and radiation (energy emitted as electromagnetic waves). These mechanisms help us understand how heat spreads in diverse situations, from a pot on a stove to the atmosphere. The theory is used to design efficient heating and cooling systems, ensure safety, and analyze energy flow in natural and engineered environments. Overall, it describes the principles behind the movement and distribution of thermal energy in the world around us.
