Boiling water in a pot on a gas stove is an example of heat transfer primarily by convection within the water.<\/section>\n
Convection is the transfer of heat through the movement of a fluid (liquid or gas). In boiling water, heat from the stove is conducted through the pot to the water at the bottom. This heated water becomes less dense and rises, while cooler, denser water from the top sinks, creating circulating currents (convection currents) that distribute heat throughout the liquid.<\/section>\n
Heat transfer in a microwave oven (A) is primarily through dielectric heating caused by microwave radiation exciting water molecules. Feeling warmth from the sun (C) is heat transfer by radiation through electromagnetic waves. Heating a brass rod (D) involves heat transfer by conduction through the solid material from the hotter end to the cooler end via molecular vibrations and free electron movement.<\/section>\n","protected":false},"excerpt":{"rendered":"
