yall know what i mean? Evaporates wat eva

It doesn't melt - it sublimates. That's when something goes straight from solid to gas without the liquid state in between.
Anyway, it sublimates at minus 78.5 Celcius.

Whether it melts or sublimates depends on the pressure. At normal atmospheric pressure, it does sublimate. However, carbon dioxide (or any gas) becomes a liquid at a high enough pressure. Therefore, if dry ice were in a tank at high pressure, it would melt.

trick question lol
Dry ice does not melt. It's made from CO2 and goes directly from solid to gas. As opposed to a regular H20 Ice cube that does melt to a liquid state.

Dry ice does not melt. It sublimates. That is to say, it goes straight from a solid to a gaseous state. Liquid carbon dioxide does not exist (at least, in nature).

Dry ice melts like regular ice, except for the temperature. The temp. is -57 C. Go through the research and see for yourself.

It is frozen at -109.3°F or -78.5°C, so anything warmer than that it would melt... although really it vaporizes or whatever.
