Fyron is correct..if this was true, letting oxygen out into space and then lighting a match would result in an explosion. It doesn't.

Hydrogen and helium make up the majority of elements because they are the simplest and take the least mass. For every, oh, carbon atom you could have TWELVE hydrogen atoms. For the metals and heavy radioactive elements, it gets even worse.

EDIT: and yes, things near 0K can be more compact. Note the can. Because as you compact them you decrease the volume and increase the pressure. The result of -that- is an increase in heat.
