Microwaves cause certain molecules to vibrate rapidly, which then transmit energy to neighboring molecules. Microwaves have the greatest effect on

The answer is Water

Explanation: Microwaves are high frequency electromagnetic waves, such as radio waves. These waves are reflected several times in the metal walls of the oven over food, vibrating the water molecules contained in it. The friction between them produces heat by cooking the food.

Answer: I believe water because the friction produced by electric waves and water molecule create heat to cook the food.
