Why does ice disapear in my freezer?

Question

I have a no frost fridge with a freezer compartment. When I put water in the ice trays into the freezer they turn into ice after a couple of hours. If i do not use the ice for a couple of weeks, the ice starts to shrink and then it disapears from the ice tray, why? where does it go?

Answer 1

When a substance goes directly from solid to gas, it's called "sublimation". That's what's happening with your ice cubes. It's also how frost-free freezers work.

Answer 2

You are observing the process of sublimation.

Sublimation of an element or substance is a conversion between the solid and the gas phases with no intermediate liquid stage. Sublimation is a phase transition that occurs at temperatures and pressures below the triple point (see phase diagram).

At normal pressures, most chemical compounds and elements possess three different states at different temperatures. In these cases the transition from the solid to the gaseous state requires an intermediate liquid state. However, for some elements or substances at some pressures the material may transition directly from solid to the gaseous state. Note that the pressure referred to here is the vapor pressure of the substance, not the total pressure of the entire system.

Frost-free freezers are the result of having a fan and air circulation inside the freezer. The sub-zero temperature combined with the air circulation that keeps the air arid, significantly accelerates the sublimation process. This keeps freezer walls and shelves free of ice, although ice-cubes will continually sublimate.

Answer 3

Because your husband it too lazy to fill the ice trays. If you are not married then it must be because of a process called sublimation where a solid goes directly to a gas. Think evaporation without the melting step. Where does it go? Who the heck knows you can't see it anymore so it must not exsist in your freezer.

Answer 4

It's most noticeable in something called freezer burn. Even though the water is in a solid state it with still evaporate. That is also why you get freezer burn. If you leave a piece of meat in the freezer for a long time it will dry out and have no meat juices at all. If you try to cook it or eat it it tastes terrible.

Answer 5

I cannot claim to understand the way it works, but your disappearing ice is merely the "frost free" function doing what it's supposed to do! If you want to keep ice cubes in a frost-free environment, then you'll have to seal them in something. You'll also find that bread will come out stale if you store it in the freezer. It just sucks out all the moisture, no matter the source!

Answer 6

you ought to upload warmth to soften. yet ice will sublimate or turn without postpone from a stable to a gasoline in a dry freezer, enormously frost unfastened. So the ice can get smaller because of the fact the outdoors floor turns to a gasoline.

Answer 7

That happens in my freezer too. The ice just simply evaporates.

Answer 8

It went to the collecting tray at the bottome and eventually evoperate. The "no frost" is nothing but a heater melting the frost and collecting the water at the bottom. Your no frost is overheating.

Answer 9

ice is the solid form of water, and like liquid water it evaporates.

Answer 10

Solid water can evaporate.
