Summary:Molecular crystals are formed by one or more kinds of molecules tiled in regular patterns in microscopic space. A common example is solid carbon dioxide, also known as dry ice, which is often used to pack and keep ice cream cold. In this activity, you will use a set of molecular models to explore how melting molecular crystals affects their atomic structure.
