Why spray alcohol on snowballs causes a lot of snow to melt

answer:

The problem is actually very simple in principle, that is, the freezing point of the water-alcohol mixture will be reduced. Although, however, alcohol cannot be used as a snow melting agent, and in addition to safety considerations, the cost is also a big problem.

One more word, I don't know if you have done a high school exercise, ask you to add alcohol to the car water tank will not freeze what is the principle, and this question is actually the same.

However, readers and friends should not add alcohol to the car water tank, alcohol is a volatile liquid, and the vapor it emits can form a combustible mixture with the atmosphere, which has the risk of causing an explosion, and the volatile characteristics are also easy to cause water shortage in the tank. In the automotive antifreeze on the market now, the main antifreeze effect is ethylene glycol, which has a high boiling point, small volatility, good thermal stability, and a low freezing point of the mixture, which is more than the ideal antifreeze agent than alcohol.
