What is the term for the process of heat transfer through the movement of fluids or gases?

The process of heat transfer through the movement of fluids or gases is known as convection. Convection occurs when warmer areas of a fluid or gas rise and cooler areas sink, creating a circulation pattern. This method of heat transfer is crucial in many natural processes, such as weather patterns and heating in buildings.

Conduction, on the other hand, refers to heat transfer through direct contact between materials, where heat moves from the hotter object to the cooler one without the movement of the material itself. Radiation involves the transfer of heat in the form of electromagnetic waves and does not require a medium, like air or water, to travel through. Evaporation is a process where liquid turns into gas and does not primarily involve heat transfer mechanisms through fluid movement.
