Red = heat. Around pipe, there's normal Earth air composition

Too much for you? A real question requiring knowledge from several areas of physics, and 0 answers. A shitty troll and you get 300.

/sci/ is a joke.

Easy-peasy answer, assuming the down arrow means A is pointing to the sky and B is pointing to the ground.

Literally made by me. But yeah whatever you say, highschool kiddo.

Answer is anything but easy

A
hot air goes upwards
but only if outside temperature is the same at A and B

>>8270801
B

>>8270801
at which point is it pressurized to 1 atm?

>>8270894
Answer is wrong. Based on what law of thermodynamics do you even base this on?

Or maybe heated metal becomes lighter too? Hot air will "go upwards" only in air in presence of "colder air", not through solid objects.

Outside and inside temperature was not specified for a reason.

>>8270904
Assume it's near the heating element

>>8270908
>Hot air will "go upwards" only in air in presence of "colder air"
but isnt there colder air inside the tube?

the pipe material is more compressed = more dense = takes more energy to heat it up at the bottom, so A gets hot faster

>>8270915
Why? Let's assume it's water. It doesn't matter either way

>>8270908
>Based on what law of thermodynamics do you even base this on?
I based it on my fridge. it's cold at the bottom drawer and warmer at the top.

>>8270927
That's probably because you got a freezing compartment on the bottom, not because of laws of physics.

>>8270933
it's got the freezing drawer on top.

>A real question requiring knowledge from several areas of physics
>heat rises

What a toughie.

>>8270923
Do you not know why hot fluids rise? Hot water still rises.

>>8270961
>heat rises

Ph.D in physics right there
lmao

>>8272133
Hot fluid is less dense, so will float to the top of colder fluid

>>8270801
Do A and B refer to the fluid on the inside of the pipe or the pipe itself?

Assuming the gas obeys the ideal gas law they should be the same temperature.

>heat source heats air
>air in side pipe becomes heated
>at the t-junction, cool air slips into the side pipe as heated air flows upward
>more hot air goes upward to A
of course this assumes OP is talking about air, not water
