What are two real life examples of expansion in solids?
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
However, when water is boiled, it's particles expand quickly depending on the temperature.
