WebConvection is the transfer of heat by the movement of a fluid or gas. It occurs when a fluid is heated, causing it to expand and become less dense. The less dense fluid then rises, while cooler, denser fluid sinks. This creates a circulating pattern, where heat is transferred from one part of the fluid to another by the motion of the fluid. WebThis is because heat is lost to the surroundings. Thus, heat transfer is the transfer of heat or thermal energy between physical systems. So when there is a temperature difference …
