Understanding Microwaves and Their Function

Microwaves are a type of low-energy electromagnetic wave. When absorbed, they cause molecules to move, generating heat. Microwave ovens utilize this property to heat food by causing water and other molecules within the food to vibrate and warm up.

What type of energy do microwaves possess?

• High-energy

• Low-energy

• Medium-energy

• Variable-energy

What happens to molecules when they absorb microwaves?

• They evaporate

• They freeze

• They change color

• They jiggle and heat up

What is the primary function of a microwave oven?

• To heat food by agitating molecules

• To cool food

• To bake food

• To fry food

Which molecules in food are primarily targeted by microwaves in an oven?

• Fats

• Carbohydrates

• Water and other molecules

• Proteins

How do microwaves generate heat in food?

• By compressing the food

• By emitting light

• By causing molecules to jiggle

• By changing the food's chemical structure
