Someone told me a liquid doesn't expand or cntract... Yet, water expands when it freezes thats why the pipes burst in basement in the cold weather.

It expands when heated and contracts when cooled. Water is the only substance I know of that expands when it freezes. Most substances contract. Heated gas will not cause an explosion by itself. An ignition source is still needed.

No-- most everything expands when heated and contracts when cooled-- even WATER for the most part. It's only at the stage when it actually turns to ice that it expands as the molecules set up in their crystal state. At most temperatures, water expands like everything else when heated.

The person who told you that was absolutely WRONG. Gas will expand under heat. As will water.... HOWEVER, when most liquds freeze, their volume increases aswell, (which is why ice floats) due to the formation their molecules take up in the solid form.
IF liquids didnt expand when they were heated, they would never evaporate! There is your proof. :-)

Liquid gas explodes when heated. I'm not sure what happens when it is cooled.

the only thing I have noticed about gas is that when it is hot the fumes expand
