What is dry ice BYJU’s?
Dry ice is just cooled and condensed carbon dioxide. It skips the melting process and sublimates directly into carbon dioxide gas when it reaches room temperature and pressure and expands. Dry Ice is manufactured by compressing and cooling gaseous CO2 under high pressure to initially produce liquid CO2.
What is the use of dry ice Class 11?
Its advantages include lower temperature than that of water ice and not leaving any residue (other than incidental frost from moisture in the atmosphere). It is useful for preserving frozen foods where mechanical cooling is unavailable. Dry ice sublimates at 194.7 K (−78.5 °C; −109.2 °F) at Earth atmospheric pressure.

What is dry ice bubble?
Explanation of Dry Ice Bubble Formation. Dry ice is a solid that directly changes into its vapor form without passing through the intermediate liquid state, a process called sublimation. It happens at a temperature of −109.3 °F. Putting dry ice in warm water accelerates the process, creating clouds of fog.
