[Science] - Which freezes faster? Hot water or cold water?

[UltimaOnline]

You'd be surprised.





Actually, the correct answer is "case by case". Science (like everything else) is a microcosm of real-life : there are multiple factors (the video highlighted 5 that contribute towards the Mpemba effect, there are of course many other factors both for and against the Mpemba effect, possibly even factors that human science on Earth may not be aware of yet) at play.


So in cases as-and-when the pro factors outweight the con factors, the Mpemba effect (which is merely an observed outcome, not the underlying mechanism, of which the video briefly touches on 5 pro mechanisms) is observed. In other cases when the con factors outweigh the pro factors, the Mpemba effect isn't observed. The former cases do not prove the Mpemba effect, just as the latter cases do not disprove the Mpemba effect. Like in real-life, there are always many multiple (including opposing) factors involved.


TLDR : It's complicated, as life should be, wonderfully.

Haha.. Sir Francis Becon was the appointed editor for the Holy Bible book during the King James period.

Then he gets Mr. Shakespeare to co edit to translate the German Vulgate Bible to English version.

The KJV Bible book was written in Shakespeare's stage Play story style with all the Thou, thy, thee, art, unto... words written into the Bible Book.
