Dry Ice Research Paper

Dry ice is frozen CO2, a normal part of the Earth’s atmosphere. CO2 is a odorless, colorless gas that can be harmful. CO2 is what plants give off when they are going through photosynthesis, what is put in soda water, and also what we exhale when breathing. The gas is captured and is recycled to make dry ice. Dry ice doesn’t melt it turns back into a gas, because it doesn’t exist in liquid form. It just not in Earth’s atmospheric pressures.

Dry ice freezing temperature is great for freezing ideas and stuff like that. It temperature of dry ice is about -109.3°F or -78.5°C. It’s easy to handle with a special kind of glove. But the reason “Dry Ice” is called that because of sublimation. “So instead of melting, solid carbon dioxide absorbs thermal energy.”(Buckley pg.53). Which means when it melts it goes for a solid to a gas without going through the liquid stage. Dry ice will keep everything frozen and freezing until it completely sublimate, but take extra time to threw because dry ice is so cold.

A good container could be a good ice chest (which is something like a cooler). These coolers or insulated container can help slow down the sublimation rate. And you want to pick it up as close to the time possible because it will began to melt or sublimate. “The best shipping container is a three-inch thick urethane insulated box tested to loose only 5 pounds for a 10-quart storage area every 24-hours.” ("How Long Dry Ice Lasts."). Also make sure you have paper or paper bags in the space where air is “dead” because it would make the dry ice sublimate faster
