comment Which one is colder? Zero temperature ice or zero temperature water?
Also, are you talking about temperature in some energy sense?

comment 2s orbital wavefunction has non-zero probability at $r=0$?
Why not? Especially the marked answer is a clear explanation that the probability isn't just a wavefunction at zero. You forget the volume, which a proportianal to $r^2$, so multiplying by zero is zero. And notice that the plot you added thave $4\pi r^2 R^2_{nl}$, and not just a wavefunction.

comment Why do lines in atomic spectra have thickness? (Bohr's Model)
Talking about Bohr model: I don't think it's explain it at all; in modern theories the thickness of absorption/emitting lines due to the uncertainty principle (the one about time-energy). And this was discovered far later than the Bohr model.
