What chemicals prevent freezing, if any?

Question

I'm not savvy with chemicals but if you could name one, that would great.

Answer 1

Anything that dissolved in water lowers its freezing temperature. Anti-freeze is a chemical added to water in vehicles to lower the water's freezing point--- It will freeze if the temperature gets low enough. That is why in some very cold northern as well as southern areas, vehichles must have a way to keep the water moving so that it doesn't freeze--

Table salt lowers freezing point of water---but there are icebergs in the northern and southern oceans.

Answer 2

sugar, salt, alcohol, ..., lots of them.

Answer 3

Nothing prevents freezing.  A mixture of two or more compounds melts (or freezes) at a lower temperature than either (or any) of them alone.

Answer 4

antifreeze
