This type of heat transfer is called convection. The fluid above a hot surface expands, becomes less dense, and rises. At the molecular level, the molecules expand upon introduction of thermal energy.

Convection: This is a transfer of heat with the circulating of liquid or gas. This process of mixing leads to rising warm air and sinking cool air. That process can be called a convective current.

The process continues, a convection current is set up and heat is transferred through the air and so through the room. A radiator heats mainly by convection – not by radiation!

A search for "air fryer recipe" on most social media platforms likely returns a flood of food videos touting quick and easy meal ideas. The market touts these devices as a convenient, clean, quick way ...

There are three different ways heat can move between objects: conduction, convection and radiation. Conduction occurs when objects are in direct contact with one another.

A recent study published in Engineering, “Indoor Thermal Environment Improvement Based on Switchable Radiation/Convection-Combined Intermittent Heating: Comparison between Conventional ...

The heat radiates up to the people, pets, and furniture directly above; once the room is warm, another form of heat transfer, convection, naturally kicks in to help circulate that warmth evenly ...
