"Are you saying you can have gas pressure next to a hard vacuum without a container? Doesn't that violate the 2nd law of thermodynamics?"

also, is thermodynamics not to do with heat???

Where does the 2nd law say that?

So and i said there is no hard vacuum.

Please read what I write.

"The second law of thermodynamics places an observation of EVERYDAY LIFE into a formal statement:
Heat flows spontaneously from a substance at a higher temperature to a substance at a lower temperature and does not flow spontaneously in the other direction."

h

🤦

So that doen't voilate it where does it voilate there rule?

thermodynamics is trying to fined a equilibrium, gravity is preventing that from happening

gravity as in the bending of spacetime ?

In other words,
Laws of Entropy (2LOT): Unless it is hindered 'purposely'; in "Nature"....
Heat Flows from Hot to Cold (Always !!)
Energy Concentrated to Dispersed (Always !!)
High Pressure to Low Pressure (Always !!).

It has NEVER BEEN VIOLATED ...

@Nico2020 What is gravity?

we are basing the whole globe model on a theory

Heat Flows from Hot to Cold (Always !!) But that isn't the case in space

its not even a theory reall or a hypothesis gravity is more like an idea

easiest way to understand is mass attracting mass

yeah thats not a fact that happens

@Minotarus You have to prove space.

@Nico2020 What's mass?

So where is the heat?

You speaking of?

Earth?

mass
/mas/
noun
1. a large body of matter with no definite shape

@Nico2020 No matter is mols or 10^23 atoms.

Wrong

Gravity is messaurbale

?

So what's mass then?

weight times accerlation

gravity is relative density thats all

this is elementary physics, come on guys. I'm gonna get some ice cream or something

Alright so a brick on the floor is under zero acceleration, so
bricks weight = 2kg
acceleration = 0 m/s^2
2 x 0 = 0
So bricks have zero mass correct?

So if it's density why does a Helium ballon fly?
B

acceleration due to gravity*

Because a helium ballon is heavier than the air sourrounding it

bricks weigh nothing

@Nico2020 So let me get this straight, you've got weight, you derive mass with gravity and you derive gravity with mass. Isn't that circular logic?

Mass causes gravity.

that's if the mass was in space

@Minotarus mass causes an acceleration does it?
