Dry ice is the solid form of carbon dioxide (CO2). ~ Dry ice has a temperature of -109.3 degrees F (-78.5 degrees C).

When the temperature around the dry ice increaces, the phases of matter changes within it, changing from a solid to a gas. This process is called Sublimation, where the object turns from a solid to a gas, skipping the liquid stage of the phases of matter.

The first man to produce dry ice was Adrien-Jean-Pierre Thilorier. Thilorier was born on February 16, 1790 in Paris, France. On Oct. 12, 1835, there was a letter from Thilorier to the meeting of the French Academy of Sciences. The letter stated that he was able to produce carbon dioxide in solid form.

Sublimation

This is a picture of dry ice subliming inside a bowl. When you add water, it sublimates faster like this picture.

This is a carbon dioxide molecule. The molecule consists of 1 carbon atom and 2 oxygen atoms.

This is carbon dioxide in a crystaline pattern. At a point when heat is applied to the solid form, it will break this organized pattern and turn into a gas.

This is a fog machine, using dry ice sublimating into the gas. This is commonly used for haunted houses or stage productions.

This is Adrien Thilorier, the first man to produce dry ice. He presented this dicovery to the French Academy of Sciences.

This is dry ice, or carbon dioxide in solid form. This, up close, is in the Crystaline pattern shown in a picture above.

This is dry ice sublimating into a gas. The dry ice sublimates when heat hits a high heat where it can no longer be in the solid form of carbon dioxide.
