First of all, READ ABOUT LIQUID NITROGEN SAFETY first! Also, you should know what to do in a worst-case scenario if it occurs.
You can buy liquid nitrogen, just mind the price, because it will usually be high. You should also not buy it from the internet, because you won't find many on sale, so you should go to a gas supplier store if you are buying a lot or if you are buying a little, a paintball or hardware store.
no.
Nitrogen is an inert element so it is not poisonous, However Liquid nitrogen is extremely cold and should you some how manage to drink a sizable amount of it it would kill you.
Liquid nitrogen is an element.
Bob discovered liquid nitrogen.
Liquid nitrogen is condensed gaseous nitrogen. When a gasis condensed it is called to be in liquid state.
The temperature of the liquid nitrogen is so low that it freezes water molecules from the air which forms as ice at the opening.

when the liquid nitrogen is boiled then it will turn into nitrogen gas.

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.
Liquid helium is a lot colder than liquid nitrogen.
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.
