is there a chemical difference between the solid and liquid states of nitrogen
Liquid nitrogen is liquid.
In the metric system, there is no difference between liquid capacity and capacity of anything else. The cubic meter is the unit for capacity, although for smaller capacities/volumes the liter which is 1/1000th of a cubic meter can be used.
You can separate nitrogen gas from liquid nitrogen by allowing the liquid nitrogen to evaporate at room temperature or by heating it to increase the rate of evaporation. The nitrogen gas will separate from the liquid nitrogen as it evaporates, leaving behind the liquid nitrogen.
There is neither a solvent nor solute in liquid nitrogen as it is not a solution. Liquid nitrogen is pure elementalnitrogen in liquid form.
It doesn't mend the pipe. The pipe will still have a leak. However, you can use liquid nitrogen to freeze the water in a pipe and create a 'freeze block' which will prevent more liquid from getting to the leak. Once the freeze block is in place, it is much easier to repair the pipe leak.
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.
one is solid and one is liquid
Solids and liquids both have definite volumes. Gasses, however, do not have a definite volume.
The boiling point of water is 100 degrees Celsius, while the boiling point of liquid nitrogen is -196 degrees Celsius. This means that water boils at a much higher temperature compared to liquid nitrogen.
liquid nitrogen boils at −196 °C (77 K; −321 °F)
The oceans are made primarily of liquid water. The atmosphere is made primarily of a mixture of gaseous Oxygen (20%) and Nitrogen (80%).
when the liquid nitrogen is boiled then it will turn into nitrogen gas.

Liquid helium is a lot colder than liquid nitrogen.
liquid nitrogen will not freeze everything. Hydrogen and helium will remain a gas when exposed to liquid nitrogen.
