The transfer of heat by the movement of fluids is known as?

The transfer of heat by the movement of fluids is known as convection. Convection occurs when a fluid (which can be a liquid or gas) is heated, causing it to become less dense and rise. As this warmer fluid rises, it creates a circulation pattern that facilitates the transfer of heat throughout the fluid. This process is essential in various applications, including heating systems, weather patterns, and even in cooking, where hot air or water circulates around food.

In contrast, conduction refers to heat transfer through solid materials directly as a result of molecular collisions, while radiation involves the transfer of heat through electromagnetic waves, which can occur even in a vacuum. Heat absorption typically refers to the process by which materials take in heat energy, which does not specifically describe the movement of fluids for heat transfer. Understanding these distinctions helps clarify why convection is the correct answer for the movement of heat in fluids.
