Liquid nitrogen is made by taking in air from the atmosphere and compressing and cooling it. Once it is cool enough, it forms a liquid. This liquid contains argon, oxygen and nitrogen. These elements are then separated and sold as a commodity. The temperature is the only difference.
is there a chemical difference between the solid and liquid states of nitrogen
The oceans are made primarily of liquid water. The atmosphere is made primarily of a mixture of gaseous Oxygen (20%) and Nitrogen (80%).
An atmosphere implies the presence of a gaseous substance (such as air, in the earth's atmosphere, which is primarily made up of nitrogen and oxygen). Space is defined as the absence of atmosphere (as pure space consists of no solid, liquid or gaseous substance).
one is solid and one is liquid
because most of our atmosphere has nitrogen in it
The boiling point of liquid nitrogen is -195.8°C and the boiling point of water is 100°C. Therefore, that's a difference of 295.8°C.
The atmosphere of the Earth is a gas, not a liquid, and although it does contain oxygen, that is just one part of the atmosphere, which is mostly nitrogen.
They are the same element as the name suggests, but due to their different states i.e. nitrogen is a gas which makes up 70% of our atmosphere and liquid nitrogen is nitrogen cooled down to -196 degrees Celsius, they have different properties.
In the atmosphere it is a gas, in the soil it its a solid, nitrogen gas can be converted to liquid in air separation plants. Also, as a liquid Nitrogen is very cold -- cryogenic temperatures. Nitrogen is stored as liquid commonly for convenience, even when gas is required, because liquid is more dense than gas and more nitrogen could be stored in the same volume. Simply, the answer to your question is nitrogen is a solid, liquid and gas depending on where you find it or how you've modified it.
In some conditions this is liquid water. Generally water exist as a gas.
Liquid nitrogen can be kept at room temperature at sufficient pressure. Otherwise, it is a gas.
