Matter Changing States

What are the three main states of matter?

• Solid, liquid, and gas

• Ice, water, and steam

• Temperature, pressure, and energy

• Hot, cold, and warm

Compared to ice, how do molecules of water behave?

• They move less freely.

• They are locked into a crystal lattice.

• They move more freely

• They bounce off one another randomly.
