Explain how a microwave oven heats a cup of water.

Question

simple version)

Answer 1

A microwave oven heats a cup of water by using microwave radiation. Here's a simple breakdown of the process:

1. Microwaves Generate Heat: The microwave oven produces microwaves, which are a type of electromagnetic wave.

2. Water Molecules Move: When the microwaves enter the cup, they excite water molecules. Water has polar molecules, meaning they have a positive end and a negative end.

3. Molecule Vibration: The microwaves cause the water molecules to vibrate rapidly. This vibration generates heat.

4. Heat Spreads: As the water molecules heat up from this vibration, they transfer their energy to neighboring molecules, warming the entire cup of water.

So, in short, a microwave heats water by making its molecules move faster, which creates heat!
