Question

What happens when electromagnetic field is applied to the food materials containing water

• A. The water molecules orient themselves according to the polarity of the field
• B. The water molecules orient attains random orientation
• C. The water molecules evaporate during the process
• D. The water molecules orient did not show any polarity

Hint:

The orientation of water molecules in the presence of an electromagnetic field is a key factor in microwave heating.

Answer 1

The Correct Option is A

When an electromagnetic field is applied to food materials containing water, the water molecules align themselves according to the polarity of the field. This is essential in microwave heating.
