I should have started that there is no movement between the molecules (in a frozen state). Your statement is more concise.

When your body metabolizes aspargusic acid it breaks down into sulfur. When you pee, they evaporate into the air quickly due to being an unstable compound.

Temperature and pressure can introduce new states of matter... Water will freeze at a temperature exceeding 3000 deg when at 18000 atmospheres. Freeze in that no movement occurs in the molecules....but it is obviously not cold. It way be that a similar occurrence of freezing accounts for what we measure as solid in the core.
