Answer:

Water #-># ice

Explanation:

Water, being one of the only substances found here on Earth that can exist in the three natural states from normal pressure, freezes and boils at relatively normal/sustainable temperatures that can be achieved in a normal environment.

When water freezes, it's particles contract (when being frozen), and then slightly expand #-># this is one example.

However, when water is boiled, it's particles expand quickly depending on the temperature.
