* Alcohol's lower freezing point: Alcohol has a much lower freezing point than water (-114°C for ethanol vs. 0°C for water). Even if the air blown over the water is very cold, it's unlikely to cool the water below its freezing point.
* Heat transfer: The alcohol in the pan will act as a thermal insulator, slowing down the heat transfer from the water to the cold air.
* Evaporation: Blowing air over the water would actually cause it to evaporate faster. Evaporation is a cooling process, meaning the water would actually warm the surrounding air instead of freezing.
To freeze a dish of water in this scenario, you would need a significantly colder source of air and a more efficient method of heat transfer. For example, you could:
* Use extremely cold air: Like dry ice or liquid nitrogen to reach temperatures below the freezing point of water.
* Direct contact with a cold surface: Place the dish of water on a frozen surface or immerse it in a very cold liquid.
Let me know if you have any more questions about freezing or thermodynamics!
