Can hot water freeze in cold air before hitting the ground?
Given the right conditions, it can. One necessary condition is that the air be very cold, on the order of -35°F or colder. If the water temperature is close to the boiling point, it is close to evaporating anyway. Now toss the water out of its cup and into the air, and it will have more surface area, increasing the amount of evaporation. A cloud of frozen ice crystals will result.
