Question

Why do icecubes, if left in the freezer too long, eventually disappear?

Answer 1

they get all freezer burnt and turn into a hard slush... right?

Answer 2

Because people use them, and then dont refill the F%$&ING ice cube trays

Inconsiderate pricks

Answer 3

I think, even in its frozen state, a kind of evaporation occurs

Answer 4

They don't disappear.....Who had ever heard of ice cubes disappearing?

Answer 5

They evaporate.

Answer 6

they evaporate as the air in the freezer is generally very dry, especially if you have a frost-free freezer.

Answer 7

I think it has to do with sublimation. When water freezes, it gives off a gas that is removed from the water (evaporation). Thus leaving less water and a smaller cube. Eventually completely becoming gas and onto the walls of your freezer.

How long are you leaving them in for for them to completely disappear?

Edit: I am not positive so do not quote it. I'm gonna look and maybe I'll let you know what i discover.
