AI Thread Summary
Heating the air in a rigid, sealed container to double its Kelvin temperature results in a doubling of the air pressure. However, doubling the Celsius temperature does not yield the same effect on pressure. This is because pressure is directly proportional to the absolute temperature measured in Kelvin, not Celsius. The relationship involves adding 273 to the Celsius temperature, which alters the proportionality. Therefore, while Kelvin and Celsius are related, they do not affect pressure equivalently in this context.

If you heat the air inside a rigid, sealed container until its Kelvin temperature doubles, the air pressure in the container will also double. Is the same thing true if you double the Celsius temperature of the air in the container?

I don't think so, because pressure is directly proportional to the Kelvin temperature and pressure is directly proportional to (273 + the Celsius temperature).
What do you think?

Thread 'Question about pressure of a liquid'

I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...

Thread 'Why is the 3 body problem unsolvable? And what will happen if someone solves it?'

I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
