Eighth Graders Learn About Liquid Nitrogen

Dr. Paul Cerpovicz of East Georgia College recently visited Cindy Smith’s 8th grade physical science classes and presented a demonstration about liquid nitrogen. Nitrogen is the most abundant gas in the atmosphere. Students learned that liquid nitrogen is a non-toxic, colorless, odorless clear substance that exists in a liquid state at an extremely low temperature. Because liquid nitrogen is so cold, it boils and produces a cloud vapor when exposed at room temperature. Dr. Cerpovicz showed how the cold affected an inflated balloon by making it shrink, causing flowers to freeze quickly, and throwing a racquetball so that it shattered and went thrown against the wall.
