Explanation:
Dry ice is solid carbon dioxide. It is primarily used to cool food products at lower temperature than what water ice can provide. It is called dry ice because it sublimes and doesn't leave any residue thar is changes from solid to gaseous state without turning to liquid.The dry ice is also called as "Cardice".
When pressure on any gas is increased then the space between the two molecules or atoms get reduced. The compression of gas makes it solid. During this, process heat energy is released. CO2 is then compressed to get converted to solid waste. This is how dry ice is made.
