Solution : The correct answer is Dry ice.

Dry ice is another name for frozen carbon dioxide. Solid CO 2 is commonly known as dry ice and it is because it follows the sublimation process and does not melt into liquid form when heated and changes directly into gas. It is primarily used as a cooling agent.
