Answer:

Dry ice is nothing more than the solid form of [tex]CO_{2}~(carbon~dioxide)[/tex].

Explanation:

It starts sublimating (goes from solid form directly to gas form) at -78.5º C, at a standard atmospheric pressure (1 atm), meaning [tex]CO_{2}[/tex] can be preserved in its solid form at temperatures lower than -78.5º C.
