Question

why does solid carbon dioxide called dry ice​

Answer 1

Answer:

Solid Carbon dioxide is called dry ice because it resembles ice, but carbon dioxide does not exist in liquid form, it sublimes straight from a solid to a gas. Hence "Dry Ice". It sublimes at –78°C becoming an extremely cold gas. It is often used in theatres or nightclubs to produce clouds, it looks a bit like smoke.

Answer 2

It is called so because dry ice is nothing but the solid form of carbon dioxide.

Dry ice is prepared by bringing molecules of carbon dioxide closer i.e. by applying pressure.
