Would the human face really freeze solid in a few seconds, when exposed to -150 degrees Fahrenheit air, like the pilot of the crashed helicopter in The Day After Tomorrow? | Munipalli Akshay Paul ||

Published by munipalli akshay paul @

Back during college days we had a little fun with a dewar flask and liquid nitrogen.

Kind of like this

Someone scooped up a handful of liquid nitrogen and threw it in my face. What do you think happened? Did my face freeze solid? No. I didn’t have frostbite either. It felt like a splash of cold water for a second and then nothing, I was dry. Quite an interesting experience really.

Liquid nitrogen is denser than air and has a temperature well below -150 F. It’s only about 3% as dangerous as you think, but nonetheless well above the dangers of the air you mention. You could get frostbite within minutes, the guy who doused his t-shirt in liquid nitrogen and then put it on did get second degree frostbite on his back, but you won’t freeze solid or anything like that.

The greatest danger is the shock you’ll suffer from breathing in such cold air. After that it’s the frostbite and the bitter cold, yes.

WHY DO SOME ANIMALS RUMINATE BY MUNIPALLI AKSHAY PAUL | JVR | 26 APRIL 2024

Published by munipalli akshay paul @
Animals like cows, oxen are called ruminant animals. They chew the semi digested food as a part of digestion. There will be four compartments in the stomach of these ruminant animals. It takes almost three days to digest the food completely. These animals will directly swallow the food they take. This food material will reach the first compartment, rumen and is softened here and also partially digested. This semi digested food will be taken back into mouth where they chew them till they are softened. This is called rumination. This softened food material now goes to the second compartment, called reticulum. There it undergoes filtration and reaches third compartment, omasum and gets digested. There after the remaining amount is totally digested in the fourth compartment, abomesum.
