If i covered someone in liquid nitrogen and hit them with a shovel, would they shatter??

Question

hypothetically speaking of course??

Answer 1

Whether or not something will shatter after it has been immersed in LN2 depends on whether the materials which compose the object become much more brittle when brought down to the temperature of the LN2 (LN2 boils at -195.8 C, -320.4 F). The shattering is pronounced when the object is composed of some amount of liquid (like water) that can become frozen when immersed in LN2.

Fruits and vegetables shatter nicely since they are composed of cells, which are mostly made of water. When dipped in LN2, the water in the cells freezes, and the fruit becomes shatterable just like an ice cube. Shattering also works somewhat well with plants and leaves for the same reason. Shattering will not typically work on objects made of cloth, for instance. When trying to gauge whether some household object will shatter or not, a good estimate can be gleaned by determining how much water the object is made of.

Since a human being is made of cells, if a body were immersed in LN2, much of it (the skin and muscle) would become shatterable. It would be interesting to see how much more brittle bones become.

Another interesting side-note: After freezing an apple, for instance, in LN2 and letting it thaw, the apple will not be the same as before freezing. It will become more mushy. Ice takes up more volume than liquid water, so freezing a piece of fruit or vegetable will cause the water in its cells to freeze and expand, breaking the cells open. When the fruit thaws, with many of its cells busted and their contents leaked out, the result is a more mushy fruit. You can try it by putting an apple in your freezer and then letting it thaw. You should also notice the skin of the apple has cracked since the apple has expanded upon freezing!

Answer 2

piers morgan, simon tells the actuality and doesnt boost fake hopes just to enable people fall he tells them from the start, the actuality no rely how harsh and to be easy hes in simple terms asserting what ninety 9.9% of the the remainder of the international is thinking yet piers is largely a prat have a sturdy day x

Answer 3

yes! But it doesnt seem quite possible to cover someone in tat at room temp since it would have turned into gas

Answer 4

That only applies to objects that are entirely chilled to LN2 temperatures.

Answer 5

not really because the liquid nitrogen would just evaporate before it hits their skin.

Answer 6

Yes, and non-hypothetically either.

Answer 7

yes

Answer 8

yes

Answer 9

HAHAHA! i just got a mental picture of that. thats funny!

Answer 10

yep
