how come ice cubes shrink after they have been in the freezer for a long time?
Answered by bobpursley
The ice sublimes to vapor over time, much like carbon dioxide, but at a much slower rate.

Well ok but why does it turn to vapor? But thanks!! This is still helpful!! :)

I'm just not understanding why something frozen could become a gas without adding heat!
Answered by bobpursley
sublime means it turns to vapor, the vapor goes off, and less ice is there.

heat is added to the ice, it takes heat from its surroundings to sublime. It does not have to seem hot to you.

Doesn't dry ice sublime even in an icecream freezer?
