Steam has a density of 0.6kgm−3 and ice has a density of 916.7kgm−3. What shall we do?
Between ice of density 916.7kgm−3, water at 0oC of density 999.8395kgm−3, and water at 100oC of density 958.4kgm−3 increasing temperature will hit vboomice of ice first then with increasing temperature as density drops, vboom100 of water at 100oC.
vboomice=3.4354∗916.710=314.9ms−1
vboom100=3.4354∗958.410=329.25ms−1
329.25ms−1 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.
