Question

What is convection? a. heat transfer through light shining on an object b. heat transfer through electromagnetic waves c. heat transfer through moving currents d. heat transfer from one molecule to another.

Answer 1

Convection is the heat transfer by the movement of fluids, such as air or water, involving the circulation of different temperature parts of the fluid.

Step-by-step explanation:

Convection is the transfer of heat through the macroscopic movement of fluids, which can be either liquids or gases. This process involves the circulation or large-scale movement of different parts of the fluid at various temperatures. Unlike conduction, which occurs through stationary matter by physical contact, convection involves the actual movement of the heated parts of the fluid transferring energy as they move. For instance, warm air rising near a heater and circulating around the room is an example of convection.
