Two Cold Shots
Dec 16, 2021 07:42:16 #
I got about a dozen shots of liquid nitrogen from my dermatologist yesterday, and last night I came into contact with dry ice.
I received my brother's annual gift of a box of meat from Omaha Steaks yesterday. Inside the cooler was a plastic bag with dry ice (-109°F). While I was removing the plastic bag of dry ice from the cooler, one finger came into contact with the ice through the plastic bag. Instant pain! That is beyond cold - and pain. Don't even consider having any living creature come into contact with that.
Liquid nitrogen is at -320°F, but getting a quick shot of it isn't as bad as the feel of the dry ice.

I have had the dermatologists’ blasts, but have managed to steer clear of touching the dry ice. I’ll take your word for it.

In my private practice I treated a lot of engineers from one of the areas large military contracting companies. They tended to be fairly technically oriented (bringing in spreadsheets of their BP readings, etc...). As I was applying liquid nitrogen to some precancerous spots on one such patient's face, he asked how cold it was. I said "minus 320 degrees". He responded while flinching a little from the pain: "Is that Fahrenheit or centigrade"? My response: "Does it really matter to you right now"?

He must not have been too much of an engineer. Absolute zero is -273.15 degrees C. -320 degrees C is not even theoretically possible.

Reminds me of a discussion here about computer CPU temperatures some time back. Someone mentioned the CPU temp being around 110° or 115° and another person asked if that was F or C. Seemed a bit of a logical answer to me.
