Flashy grape

The video explains how microwaving a grape can lead to ionization. It begins by describing how microwave ovens work, using electromagnetic radiation to heat water molecules in food. The grape, when cut in half, acts as a dipole antenna, creating high voltage and causing ionization.

What is the primary function of electromagnetic radiation in a microwave oven?

• To change the color of the food

• To cool down the food

• To freeze the food

• To vibrate water molecules and heat the food

Why is a grape considered a perfect size dipole antenna for microwaves?

• Due to its sweetness

• Because of its size and shape

• Due to its water content

• Because of its color

What happens when a grape is cut in half and placed in a microwave?

• It ionizes

• It freezes

• It melts

• It changes color

What causes the high voltage between the grape halves in the microwave?

• The grape's temperature

• The thin skin separating the halves

• The grape's sweetness

• The grape's color

What is the result of the ionization process in the grape?

• The grape becomes cold

• The grape becomes solid

• The grape emits light

• The grape changes color
