Because some chemicals in the alcohol has a freezing temperature lower than that of H2O.
Anti Freeze it also has Propylene Glycol.
1. Today the Mpemba effect remain unclear and possible not true. 2. I suppose that any link exist between the so called Mpemba effect and the freezing of rubbing alcohol.
Well, isn't that a happy little question! When you mix water and rubbing alcohol together, the freezing point of the solution will be lower than that of water alone. This means it will be harder for the mixture to freeze compared to plain water. Just like creating a beautiful painting, experimenting with different materials can lead to interesting results!
No, it is only a physical change since the chemical properties of alcohol do not change.
Alchohol doesnt freeze in your freezer because the freezing point of alcohol is much lower than that for water. Each substance has different specific freezing and boiling temperature. Since most foods contain water, that is what freezes. Things that have alcohol boil/catch fire faster and they freeze at a very low temperature. The freezing point of ethyl alcohol is -117.3 C, or -17,914 F. Therefore you can freeze alcohol but most people think it doesnt because the average freezer doesnt even get close to -17,914 F. Technically, alcohol can indeed freeze. It just does not freeze as quickly as water. The reason is because the freezing point for alcohols is quite a bit lower than the freezing point for water.
no

a cool well ventilated area i store mine in the back garden inside a freeze box (unfrozen)
It doesnt freeze.
Windshield washer fluid already has isopropyl alcohol in it. No matter how much you put in, there will always be a freeze point - the alcohol will lower the freeze point, but cannot prevent it from happening. The container you buy the washer fluid in should tell you what temperature it's supposed to work to.

Not entirely sure you're asking but if you mix dry ice with rubbing alcohol (91%) the temperature of the liquid will drop to around -120 degrees F. It will not freeze but instead for a liquid nitrogen like liquid.
Pop will freeze at 32 degrees. Pure alcohol does not freeze at all.
no it doesnt
The melting point of rubbing alcohol, which is mainly composed of isopropyl alcohol, is around -88 degrees Celsius (-126 degrees Fahrenheit). This means that it will freeze and solidify at temperatures below this point.
No, it is only a physical change since the chemical properties of alcohol do not change.
