Practice Post

Get ready for your Chapter Challenge with these practice questions!

Why does a cold glass of water get wet on the outside after a while?

This is because hot air (which has steam in it) hits the cold glass. The cold glass cools down the air, turning it into a liquid. That's why your glass gets wet.

What is hardness?

It is how difficult it is to scratch or break matter. A diamond is very hard.
