Which describes how a microwave transfers heat to leftover mashed potatoes?

radiation excites the motions of water molecules in the food, raising their total kinetic energy

the hot oven comes in contact with the cold food and heat is transferred until both are at the same temperature

heated air currents circulate around the food, transferring their kinetic energy to the food particles

spinning the food on a turntable transfers kinetic energy to the food particles

radiation excites the motions of water molecules in the food, raising their total kinetic energy

Explanation:

Microwave is an electromagnetic radiation that conducts heat by radiation. Microwaves heat up the water molecules which then heats up the surrounding food. Microwaves cook food inside out. As the microwaves are transferred by radiation it increases the vibration of the water molecules, which is turn creates friction between the water molecules causing them to release heat to the immediate surrounding thus heating up or cooking the nearby food particles.
