Web8 jul. 2024 · Radiation is how the heat in a microwave oven is transferred. Microwaves are extremely adept at exciting and vibrating water molecules, and since food is mostly water, the vigorous motion of the molecules creates intermolecular friction, which generates the heat to cook the food item. One day, after walking past a microwave radar he’d been ... Web16 jun. 2024 · Microwaves cook food by heating water molecules within the food. Put another way, microwaves cause water molecules to vibrate, and this vibration produces friction, which converts the water into steam, which, in turn, heats and cooks food. MYTH 3: Microwaved food is less nutritious than food cooked in a conventional oven. family grievance
