I heard hot water freeze faster when thrown in freezing cold air, because it evaporates faster - making smaller droplets and increasing the surface area
It requires very specific circumstances. Given the same ambient temperature hot water will cool at a faster rate than cooler water because of the greater temperature differential.
Hot water will lose more mass as more will evaporate as it cools.
In 2016, Burridge and Linden defined the criterion as the time to reach 0 °C (32 °F; 273 K), carried out experiments, and reviewed published work to date. They noted that the large difference originally claimed had not been replicated, and that studies showing a small effect could be influenced by variations in the positioning of thermometers: “We conclude, somewhat sadly, that there is no evidence to support meaningful observations of the Mpemba effect.”
I will believe that warm water freezes faster only if I see it with my own eyes. It just goes against everything I know about thermodynamics.

Right, I can believe that. I was thinking of making ice cubes, which is also something I heard.

It’s one of those “wacky” physics facts.
I’m with those guys.
