Icebergs float on water because the underlying liquid water has a higher density than the iceberg. Liquid water itself has ...

Explain that another change in state is when liquid water cools enough and freezes to form ice. Instead of changing from a liquid to a gas, like in evaporation, the water molecules change from the ...

Water molecules freeze in a hexagonal pattern and the molecules are further apart than they were as liquid water. Water is unusual because its molecules move further apart when it freezes. The ...

A team of researchers has uncovered a previously unknown phenomenon that could improve the way we design materials at the ...

Substances can exist in three states of matter - solid, liquid and gas. Substances can change states. To change the state of a substance energy must be transferred to, or from, the substance.
