Question

which gas is called dry ice? why ? can we call this gas sublime

Answer 1

Dry Ice is the common name for solid carbon dioxide (CO2). It gets this name because it does not melt into a liquid when heated; instead, it changes directly into a gas (This process is known as sublimation).

Dry ice is the solid form of carbon dioxide. Gas can be converted to solid by the process of deposition. IN this process gas can be converted directly into solid without passing through liquid stage. From a gas ,the co2 needs to be converted into a liquid before it can become solid dry ice

Hope this helps...

If does plz mark me...
