Hey, /sci/. I always have my non-science friends come to me and

Refrigerators get hot bro. It's about redirecting heat elsewhere in order to make one localized portion of the refrigerator cold.

>>8830172
Yeah, I get that they have to redirect the heat out of it, but how do they get the cold inside?

>>8830168

Molecules have to overcome each other's attractive force in the expansion value causing them to slow down/cool down and suck in heat from the surroundings. Then they are compressed (work done here since gases want to equalize their pressure in the whole volume), and they regain the energy from separating them causing them to speed/heat up. This heat is vented out in the back.

Haven't you done thermodynamic yet?

>>8830185
I skipped thermodynamics and paid some indian kid to take it for me. It's not important for what I want to do.

And there goes another one down the drain!

>>8830168
once you take thermodynamics it will all become clear.
(Aerosp.E) Basically your electric runs a pump in the refrigerator that pushes refrigerant through a throttle that basically creates a difference of heat on either side. The cold side goes into the refrigerator and the hot is directed usually to the back or bottom of the refrigerator.

This doesn't break thermodynamics because (since you are introducing work to your room system in the form of electricity) the net heat of the area surrounding the fridge increases.

In other words if you leave a turned on open fridge in a room the room will become hotter, because the only work or heat that is entering the system of the room is the electricity going into the fridge.

I'm also going to assume that this was a joke because just about every field or occupation of engineering has thermodynamics involved. It's part of the laws that govern how the universe works after all.

and if you aren't joking I wish you the best of luck doing some dog shit job you'll never get out of, especially if you let loose somewhere that you don't understand basic thermo, which will inevitably come up sometime in your career.

>>8830457
Homie, he's full of shit. Hell, it doesn't even take thermo to know how a fridge works. That shit is covered in high school chemistry and physics. It's also usually brought up at a high level in middle school physical sciences, not to mention the billion and one sites that explain how fridges work.

It's shit bait that you should feel bad about biting on.

lmao ur dumb as fuck dude take a chemistry course, retard

chemical reaction (with REFRIGERANTS) = cold on the inside, heat is vented outside. this is why its really warm behind your minifridge

they actually produce excess heat, if they produced excess cold we could just make a bunch of fridges, or one really big one, and solve global warming

fucking brainlets
