What is a common use of convection in everyday appliances?

Convection plays a significant role in the function of cooling fans in computers. These fans operate by moving air across the electronic components, helping to dissipate heat generated during operation. As the warm air is expelled, cooler air is drawn in, creating a continuous circulation that maintains optimal operating temperatures. This process is essential to prevent overheating, which can damage sensitive components and reduce the performance and lifespan of the computer.

In contrast, electric heating for stoves primarily relies on conduction and radiation to transfer heat rather than convection. While radios and lighting fixtures do involve energy transfer, they do not utilize convection as a primary mechanism for their operational function.
