Nitrogen Family

Nitrogen

• Nitrogen is used as a refrigerant. When it is in a liquid form nitrogen is very cold. Scientists use that cold nitrogen to keep things frozen

Nitrogen

• Even though we breathe oxygen from the air, did you know that over three quarters of the air is made up of nitrogen? Let's say you had one hundred pennies. Take 78 pennies and put them to the side. That's how much nitrogen is in the air

Nitrogen

• Plants need nitrogen to grow. They get the nitrogen out of the soil that they grow in. The nitrogen is sucked in through the roots and pumped all the way up to the leaves. That's a long way if that tree is fifty feet tall
