1044. How does dry ice work to freeze things? — JH
Solid carbon dioxide or "dry ice" sublimes into gaseous carbon dioxide at a temperature well below 0° C. Since it takes energy to separate the molecules of carbon dioxide from one another, the dry ice absorbs heat as it sublimes and takes that heat out of any warmer objects nearby. Those nearby objects become colder and colder as the heat leaves them and eventually they begin to freeze.
