Baking a cake in the oven primarily involves **convection** and **conduction** as methods of heat transfer, rather than radiation.
- **Convection**: The oven heats the air inside, creating a temperature difference between the hot air and the cake batter. This temperature difference causes the hot air to rise and circulate around the cake, transferring heat to it. This process is known as convection.
- **Conduction**: The heat is transferred from the hot air to the outer layers of the cake, and then it gradually conducts through the cake's interior. Conduction is the process by which heat moves through a solid substance, from a region of higher temperature to a region of lower temperature.
Radiation, on the other hand, involves the transfer of heat through electromagnetic waves, such as the way the sun's energy reaches us on Earth. While some radiant heat may be present in an oven, it's not the primary method of heat transfer when baking a cake.
