Yes. It can freeze you to death, and can also asphyxiate you, if you breath it's off gassing exclusively, over time.
when the liquid nitrogen is boiled then it will turn into nitrogen gas.
Liquid helium is a lot colder than liquid nitrogen.
Liquid nitrogen has no melting point. A melting point is the temperature when a solid turns into a liquid. Since liquid nitrogen is already a liquid, it has no melting point. It is already melted, compared to solid nitrogen.
Liquid nitrogen is a pure substance because it consists of only nitrogen molecules in liquid form.
Generally speaking, methane gas can be "soluble" in liquid nitrogen if it was bubbled into it. Liquid nitrogen is cold enough to liquefy methane gas, and the liquid methane would then be miscible in the liquid nitrogen.
i think so doesnt it kill just about every thing?
Certainly will do. It's very cold! Is it around -80C?

No. Nitrogen does not irritate skin. But liquid nitrogen is extremely cold, and it can damage and kill skin (and other) tissue. It is a bad idea to allow your skin to come into contact with liquid nitrogen. Note: Some warts are "frozen" in an effort to remove them. In a clinical setting, liquid nitrogen is sometimes used to super-cool an instrument so the wart can be frozen. But this is a medical procedure and is done by professionals. Liquid nitrogen is not something that should be looked upon as a "toy" or "recreational plaything" by anyone.
Liquid nitrogen is liquid.
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.
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.
There is neither a solvent nor solute in liquid nitrogen as it is not a solution. Liquid nitrogen is pure elementalnitrogen in liquid form.
The liquid nitrogen is prepared by fractional distillation of liquid air.
Nothing can kill nitrogen as nitrogen is not alive. There is no reaction between sugar and nitrogen.
Liquid nitrogen is quickly evaporated.
