Ice, Water And Steam

These are density (kgm3) values for water at different temperature oC,

+100    958.4
+80     971.8
+60     983.2
+40     992.2
+30     995.6502
+25     997.0479
+22     997.7735
+20     998.2071
+15     999.1026
+10     999.7026
  +4     999.9720
    0     999.8395
−10     998.117
−20     993.547
−30     983.854

Steam has a density of 0.6kgm3 and ice has a density of 916.7kgm3.  What shall we do?

Between ice of density 916.7kgm3, water at 0oC of density 999.8395kgm3, and water at 100oC of density 958.4kgm3 increasing temperature will hit vboomice of ice first then with increasing temperature as density drops, vboom100 of water at 100oC.

vboomice=3.4354916.710=314.9ms1

vboom100=3.4354958.410=329.25ms1

329.25ms1 is very close to the sonic boom, vboom100 is the reason why the spout of the kettle made to taper, whistles when water boils.  A narrowed opening increases vboom100 to a sonic boom.  Of all the particles involved the most likely candidates responsible for the whistle are g+ and g, because steam escaping from the spout of a boiling kettle is not at sonic boom speed, but the disintegrated particles are.

Latent heat is nuclear.  Latent heat is due to resonance at vboom.  Latent heat is not reversible.

Logic takes a second place when you guess.  Courage takes first place.
