Question

Why is solid carbon dioxide called dry ice?

Answer 1

Dry ice is called dry ice because the solid turns to gas when heated, without turning into a liquid first. However, if we apply pressure and heat, we can turn it into a liquid, and sure, we can swim in it. We know this because of something called the phase diagram of carbon dioxide (the "stuff" of dry ice).
