Mini-Quiz: States of Matter

by Ron Kurtus (updated 8 February 2022)

Take this Mini-Quiz to check your understanding of the lesson material.

1. Why won't a gas stay in a cup?

The gas will stay if you hold the cup upside-down

Its molecules have too much energy to stay confined

You can't put a gas in a cup

2. Can copper ever be a liquid?

Copper is only used in making coins

Copper is a metal and can't be a liquid

Yes, it can be melted at high temperatures

3. What is a possible reason that iron is a solid, while H2O is a liquid at room temperature?

Iron atoms are harder than water molecules

Iron atoms have greater mass than water molecules and thus require more energy to go to the liquid state

Adding water to iron changes it to the rust state of matter

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.
