cold

[jack grebe]

define cold. what is it. from what I learned in school, there is only heat in varing degrees

[Garrett Lowell]

Which do you prefer: adjective, noun, adverb or verb?

[Popeye]

you confusing thermodynamics with sensory perception

[jack grebe]

still....there is only heat and lack of it

[cedar savage]

Yer werkin up a sweat out in da cedar swamp. It's thurdytree below. Ya stops fer a chaw of RedMan. Ya spits yer chaw and it goes "snap" as it freezes before it hits da groun. Dat dere is as good a daffynition of cold as yer gonna git.

When all the cars and trucks have electric cords coming out the front. that's cold. Like in Lake Placid or Old Forge where they don't talk windchill; 30 below is 30 below.

I love that saying, popeye, particularly when people look at me with shock. Then I explain it to them.

I was good friends with my high-school unified calc teacher. He used to be a Bell Labs scientist then he had bypass surgery, one of the first by Dr. Debakey down in TX. After the heart surgery he became uninsurable and so he went to work in a high-school for the benefits. Anyway he was a cool old guy looked kinda like a balding Einstein and met his wife when they were both working at Los Alamos ya know some NY project Anyway again, they were moving and I offered to help. I remember I was moving the refrigerator and grabbed the back where the coils were. It was hot and I said why would a refrigerator be hot? His reply was "cold is only the absence of heat" This lead into a long conversation about thermodynamics and entropy well into dinner where true to entropy very little packing took place. I miss that teacher, he is one of those you carry with you for the rest of your life.

cold enough to freeze the nuts off a steel bridge

[Memphis Mike]

OK Joe. So why are the coils on the back of a refrigerater hot and for that matter any condensing unit?

[PatCox]

Cause when you compress a gas it heats up, when you release the pressure it cools off. When it heats up, it releases heat into its surroundings, when it cools off, it sucks heat out of its surroundings.

So if you put compressed gas into a bunch of pipes and allow the pressure to rapidly fall, those pipes will get cold. Put those pipes in an insulated box and call it a refridgerator. The pipe then leads out of the box to the compressor, where it is compressed, the pipes leading out of the compressor will therefore be hot, keep those out of the box.

popeye asks:

soo .. trivia, what's a 'brass monkey' then ?

A 'brass monkey' was the stand used to hold a stack of iron cannon-balls in a lovely, tight, geometric arrangement. In extreme cold, the difference in contraction (between the 2 metals) would cause the cannon-balls to 'break formation' and jump out of the monkey.
What do I win?

Bullcrap! Brass monkey is this rather fruity drink with rum and vodka and orange and pineapple juice that fraternity boys use to try remove the panties of sorority girls. I thought everybody knew this.

Sorry for the thread drift; now back to the absence of heat discussion.

Colder then a brass toilet seat on the shady side of a glacier.....

Cold is the absence of heat.

Dark is the absence of light.

Evil is the absence of good.
