Final answer:
Convection is the transfer of heat energy between a solid and a moving fluid. It occurs when a fluid becomes heated and rises, carrying the heat energy with it. This type of heat transfer is commonly observed in weather systems and forced-air furnaces.
Step-by-step explanation:
Convection is the transfer of heat energy between a solid and a moving fluid. It occurs when a fluid becomes heated and rises, carrying the heat energy with it. Conversely, cooler fluid sinks, creating a continuous cycle of hot air rising and cool air sinking. This type of heat transfer is commonly observed in weather systems and forced-air furnaces.
