Pretty much all substances expand when heated. The maximum density for water occurs at around 4 degrees Celsius. If you heat it up or cool it down from there, it will expand.
Water is the only substance (known) which expands upon freezing.

Surely you mean expands when cooled (frozen into ice), because everything else expands when heated, even water. There is no other naturally occurring substance which has that property of expanding on freezing. It may be possible to synthesize some.

Water contracts in volume when heated and expands when cold.

I'd guess that you're asking if there are other substances which, like water, expand when they're frozen. Antimony is one.

everything expands when heated. Only water expands when you freeze it.

Water expands when it is frozen, not heated.

ALL SUBSTANCES EXPAND ON HEATING AND COMPRESS ON COOLING.
The thing is, they do this only a little so we can't notice it with our naked eye.

everything almost.
molecules in the substance increase KE causing them to move farther apart.

solids and gases.
what is meant by expansion is that the individual particles gain heat energy, start to move (more for gases and liquids) and move away from each other.
hope this helps.

metals, like iron and also good example railway tracks
