I imagine it as 2 speakers each playing whitenoise which would repel more the louder they’re playing, though I’m probably far off in some context or another. Heat raises pressure, so they are pushing on eachother more somehow. But whats happening between them at the farther distance?
In: Physics
You are mixing up scales. Sure higher heat = higher pressure but thats only for groups of molecules, very very large groups.
Hot or cold for individual atoms just means how fast they are moving, how much kinetic energy they have. It won’t impact how they repel/or attract other atoms, it just increases the frequency at which they collide (and the energy at which they do so, usually making them more likely to react).
Think of them like bumper cars (assuming no reaction). Faster cars means bigger bump, but the distance at which it bumps is the same.
