What is a dry ice and what are its applications 

Dry ice is great for adding a smoky scene to any party, and for many, that’s all they know about this ice. The truth of the matter is that dry ice is used to transport food, and the medical community is used to transport items like tissue samples. This type of ice can be purchased for commercial or personal use. These machines can be found at various price points.

What is dry ice?

Dry ice is a unique substance with a variety of uses. Essentially, dry ice is frozen carbon dioxide (CO2). The first report of what we now call dry ice came from French chemist Charles Thilorier in 1834. In 1924, the American Dry Ice Company registered the solid form of CO2 as “dry ice,” as it is commonly referred to today. 

Frozen carbon dioxide is also much colder than regular ice. Ordinary ice freezes at 32 degrees Fahrenheit, while carbon dioxide goes from gas to solid at -109.3 degrees Fahrenheit. This extremely cold temperature makes it very dangerous to operate with bare hands. It can cause frostbite in a very short time. 

The reason it’s called “dry ice” is that it’s actually dry — it doesn’t get wet. At normal atmospheric pressure, CO2 changes directly from a solid to a gas. It skips the liquid phase that makes regular ice look wet.

6 main uses of dry ice

Over the past century, dry ice has been used for a variety of commercial, industrial, scientific, and domestic purposes.

# The main use is to refrigerate food when electric refrigeration is not available. Through the process of sublimation (when CO2 changes from solid to gas), it can keep food cold for a long time.

# If you’ve ever been to a haunted house or play and saw heavy fog on the ground, chances are you’ve seen dry ice at work. This effect is achieved because carbon dioxide is heavier than air, so the evaporated carbon dioxide sinks and accumulates on the ground. This is far superior to most artificial fog machines that use other methods, as artificial fog often rises like smoke.

# It is also often used in scientific laboratories for similar purposes. Frozen carbon dioxide can be used to keep cellular tissues and other important heat-sensitive materials at low temperatures.

# Another interesting use of this substance is to trap insects such as mosquitoes. These insects have sensors that attract them to carbon dioxide. They found that the high concentrations of carbon dioxide found in dry ice were irresistible.

# Doctors and brave people also use it regularly to remove warts and other unsightly blemishes from the skin. By applying a small patch of frozen carbon dioxide and some pressure to the wart, it will effectively freeze and kill the tissue, making it easy to remove.

# In the 1960s, scientists speculated that Mars’ polar ice caps were made of frozen carbon dioxide. Recent observations suggest that while the topmost layer is composed of dry ice, most of it may be ordinary frozen water.
