Convection: meaning, definitions and examples

heat transfer

Convection refers to the process of heat transfer through the movement of fluids (liquids or gases). It occurs when warmer, less dense fluid rises while cooler, denser fluid sinks, creating a circulation pattern. This mechanism is fundamental in various natural and artificial processes, including weather patterns, cooking, and heating systems. Convection can be classified into natural convection, driven by buoyancy forces, and forced convection, facilitated by external means such as fans or pumps.

• Heat travels by convection in a boiling pot of water.

• The Earth's atmosphere showcases convection patterns that influence weather.

• Convection ovens cook food more evenly than traditional ovens.

• Natural convection occurs when warm air rises in a room.
