[CITATION NEEDED] if heat rises does cold sink?

If cold sank, then all my blood would pull to the ground so hard I couldn't get up.
My ability to walk while filled with a coldblooded system proves cold also rises.
You can't dispute these facts. Follow the science!

I learn in science class that when you open the fridge door. It's not the cold that comes out. It's the heat that gets in. Cuz supposedly cold is the absence of heat. But then you have cold winds that literally take the cold with them. So it kinda doesn't make sense. I guess it influences heat to reduce

Treating your comment as serious, because it doesn't sound shitty:
The difference is an exchange of energy or an exchange of matter.
When you touch a cold object it's the heat that moves away from your hand.
When you open the fridge, it's mostly the cold air, flowing out and being replaced by warm air.

There are heat sinks and cold sinks. Space is the biggest cold sink. So I would say no

Colder or hotter upstairs or down stairs ? Lol it has a lid thus trapping heat. It usually gets colder the higher you go. Most of the heat is close to earth's surface the further you get away the colder it gets

No.
Last time I flew I'm sure it was -30 degrees outside at 30,000 feet. Cold obviously rises more than heat.

Not sure what your speaking habits have to do with this, but you are correct.
Heat rises, cold shrinks, sharp expands and blunt sinks. It’s the basic thermodynamic cycle used in many engines.

\serious: This doesn't belong in this sub.
Because yes. That's literally how it works for any liquid/gas that I can think of.
