what tpe of heat transfer is cooking food in the microwave

Answer 1

The primary mode of heat transfer in cooking food in a microwave is through radiation. Microwaves, which are a form of electromagnetic radiation, excite the water molecules present in the food, causing them to vibrate rapidly and generate heat. This heat is then transferred to the rest of the food, cooking it. Some convection may also occur within the food due to the movement of heated air molecules, but it is not the primary mechanism of heat transfer in microwaves.
