What is dry ice & what are its uses?

Dry ice is the solid form of carbon dioxide. It is also called as " Cardice " or as " card ice ".
At temperatures below −56.4 °C (−69.5 °F) and at below 5.13 atm pressure (the triple point ), carbon dioxide gas changes from a solid to a gas with not converting into liquid, through a process called sublimation.

Uses of Dry Ice-

*. Dry ice is used primarily as a cooling agent. It is useful for preserving frozen foods, ice cream, etc., where mechanical cooling is unavailable.
*. To remove floor tiles.
*. To remove skin imperfections.
*. In the poultry industry.
*. To lengthen the life of wet ice.
*. To make fog in the entertainment industry.
*. To shrink metal.
*. To retard chemical catalysts.
*. As a mosquito attractant for traps.
*. By airline caterers to keep food chilled.
*. By blood banks for shipping the blood.
