In baking, heat is transferred through convection, conduction, and radiation. Convection occurs when hot air circulates in the oven, transferring heat to the food. Conduction happens as heat is directly transferred from the hot baking pan to the food. Radiation is the transfer of heat from the oven walls or heating elements to the food through electromagnetic waves.
Radiation is the type of heat transfer that occurs in the form of waves. This transfer of heat can occur through empty space and does not require a medium. Examples include sunlight and heat transfer from a fire.
Convection is the type of heat transfer that occurs in only liquids and gases. It involves the transfer of heat through the movement of the fluid molecules due to differences in their density and temperature.
Heat transfer in an oven when baking a cake occurs through convection, conduction, and radiation. The oven's heating element or gas flame produces heat, which is then transferred to the air inside the oven through convection. The hot air circulates around the cake, transferring heat to the batter through conduction. Additionally, the walls of the oven emit infrared radiation, which also contributes to heating the cake.
Heat transfer by Brownian motion takes place only in fluids (liquids, gases, and plasmas).
The form of energy transfer that occurs when heat is transferred from one object to another is called conduction.

Baking soda is not a good conductor of heat. It is a poor conductor due to its low thermal conductivity, which means it does not efficiently transfer heat.

Heat transfer in liquids and gases occurs primarily through convection, which is the transfer of heat through the bulk movement of the fluid. In convection, the hotter fluid rises and the cooler fluid sinks, creating a circulation pattern that transfers heat. Conduction, the transfer of heat through direct contact between molecules, also occurs in liquids and gases but is less efficient compared to convection.

Heat transfer occurs when a kettle is placed on a lit gas ring, and the water is brought to the boil.
