Q. Statement I: For cooking in a microwave oven, food is always kept in metal containers.
Statement II: The energy of microwave is easily transferred to the food in metal container.

 2178  200 Electromagnetic Waves Report Error

Solution:

The atoms of the metallic container are set into forced vibrations by the microwaves. Hence, energy of the microwaves is not efficiently transferred to the food. Hence, food in metallic containers cannot be cooked in microwave oven. Normally in microwave oven the energy of waves is transferred to the kinetic energy of the molecules of the food. This raises the temperature of any food.
