Question

what is dry ice and why is it known so?

Answer 1

Dry ice,is the solid form of carbon dioxide Carbon dioxide gas turns to dry ice when the temperature drops to -110° F. ... When dry ice is warmed above -110° F, it changes from solid dry ice straight back to carbon dioxide gas. Since it never passes through the liquid phase, it's called dry ice

Answer 2

Hii...

When CO2 is kept under high pressure and lower temperature it converts into its solid form known as dry ice .

Dry ice is called so as it never passes through liquid state ,it is directly a conversion of gas to solid .
