I am definitely not a science person, so this may be a really obvious/dumb question, but I don’t get it. My understanding was that most things expanded when heated, but sodas/beers seem to expand violently when they’re frozen. Can someone explain this like I’m five?

Water is a very interesting chemical. When liquid the molecules of H2O can move around freely whereas, when solid, the molecules are held in place by intermolecular forces. As a liquid the molecules are able to be close together but when it decreases in temperature those intermolecular forces hold the molecules apart. Water is most dense at about 4 degrees Celsius. Any hotter and the water expands, any colder and the forces hold molecules apart.
