Liquid becomes a solid at freezing temperatures, but alcohol (vodca), very much a liquid, does not freeze. Why?
Answer 1:

It will freeze ......you just have to go to lower temperatures. It is the same with melting...some materials melt at low T and some not until very Hi T is reached. It depends on the strength of the bond between the constituent atoms making up the fluid or solid.


Answer 2:

Different liquids have different freezing points.Water freezes at 32degF where alcohol freezes at a much lower temperature (-172degF). That is why putting salt on the roads keeps the water from freezing. Salt reduces the freezing point of water to 28degF.


Answer 3:

Different liquids have different freezing points. Water freezes at 0 degrees C. Rock freezes at over 1000 degrees C (the liquid form of rock is known as lava). Alcohol freezes at a lower temperature than water, so will remain liquid at temperatures where pure water will freeze.
