1. Why does water boil at a lower temperature on a mountaintop?

It is hotter when you are closer to the Sun

There is less pressure to contain the water molecules

You can't boil water on a mountaintop

2. What can happen when the pressure of a material is less than that of its Triple Point?

It can go directly from a solid to a gas

It always goes directly from a solid to a liquid

It can be in three states at one time

3. Why does water expand when it turns to ice?

All materials expand when cooled

The crystalline structure of ice causes it to expand

Water cannot be compressed

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.
