TECHNICAL FACTS OF FROZEN CO

Dry ice is frozen carbon dioxide (CO
Traditional ice is 0°C (32°F). In addition, dry ice does not melt, it sublimates. Sublimation is the process of going directly
from solid form into gas form. Dry ice by-passes the liquid form, hence the "dry" ice.
The first step in producing dry ice is to turn the carbon dioxide gas into a liquid. This is done by compressing the CO
removing excess heat. Next, the pressure is reduced over the liquid carbon dioxide by sending it through a snow valve
(expansion valve). As the liquid evaporates, it absorbs heat, causing some of the CO
dry ice snow is then exposed to compaction first in to pellet form and then reformed by a large press to form blocks/slices.
Dry ice is much heavier than traditional ice, weighing 1.7 times as much. CO
combustion of organic compounds and is exhaled by humans and other living beings.

CO is:
2
:: Non-toxic
:: Transparent
:: Odourless gas under atmospheric pressure and temperature
:: 1½ times heavier than air
:: The atmosphere consists of 0.03% CO
CO exists in three forms:
2
:: Gas, e.g. used in the food industry
:: Liquid, kept under pressure
:: Solid, dry ice
