Heat transferred by the movement of a fluid is known as?

Heat transferred by the movement of a fluid is known as convection. This process occurs when a fluid (which can be a liquid or gas) moves and carries heat with it. As the fluid moves, it transports thermal energy from one place to another, resulting in temperature changes in the areas it flows through.

For example, when air is heated by a radiator, it becomes less dense and rises, creating a circulation pattern that allows cooler air to be drawn in and heated in turn. This continuous movement of the fluid helps efficiently distribute heat throughout a space, making convection a key mechanism in heating and cooling systems.

Convection differs from conduction, where heat is transferred through direct contact between materials, and radiation, which involves the transfer of heat in the form of electromagnetic waves without a medium. Sensible heat refers to the heat that causes a change in temperature of a substance without changing its phase, but it does not specifically pertain to the movement of fluids. Thus, convection is the correct term for heat transfer through fluid movement.
