Sublimation

Absolute zero

Removed "The only way to prevent freezer burn is to have a freezer capable of reaching absolute zero, -459.67 degrees Fahrenheit (-273.15 degrees Celsius), where according to the Third Law of Thermodynamics, all molecular movement ceases. However, since achieving absolute zero is physically impossible, and since the normal freezer temperature is 0 °F (-18 °C), there is no way to completely prevent freezer burn." because if the only way to do something is impossible, then it is not a way to do something.

Basic chemistry

I seem to remember reading in my basic chemistry book that sublimation of water will cease around -150 degrees. Can anyone confirm/deny with a reference? 71.114.146.94 (talk) 23:55, 7 February 2009 (UTC)[reply]

Comets exist because the water does not sublimate readily at low temperature. According to Phase Diagrams — Discussion — phases & pressure the temperature at which water ceases to sublimate upon cooling (or begins to sublimate upon warming) is −121°C. Sublimation temperature rises with pressure. According to the above reference, at a pressure equivalent to Mars (1% that of Earth) sublimation temperature will be −75°C, but according to the phase diagram shown for water, there is no gas phase below 200K (−73°C), which I find confusing. I hope someone can clarify this for us. --Ben Best (talk) 02:49, 8 February 2009 (UTC)[reply]

Chemical properties

There is some chemical property of freezer burn, in this I mean that a volatile is release, hense the smell. What chemical or chemicals cause the smell of freezer burn, which is unchanged from food to food. Perhaps just the lysing of the cells release some common voltile found in most foods? 136.165.68.135 (talk) 21:10, 14 February 2008 (UTC)[reply]

Disappearing ice cubes

I have removed

For example, ice cubes in the freezer will shrink and eventually disappear.

The water won't diappear, it will be redistributed as ice on the walls of the freezer. Also, what is "eventually"? Would it take thousands of years, so that in practice the freezer would fail first? —DIV (128.250.247.158 (talk) 09:19, 22 February 2009 (UTC))[reply]

"The water won't diappear [sic]..." The sentence isn't discussing any 'loss' of water, but the disappearance of the "ice cubes" proper; they do, in fact, disappear. It's a nice illustration of sublimation as pertaining to a localized disappearance of the (frozen) moisture in the meat and hence its dryness. Whether it reappears on the freezer walls or Pluto (or simply vanishes into the void in flagrant violation of the law of conservation of matter/energy) is immaterial to the disappointed carnivore.

Dead link

The link referenced by the number [1] is nonfunctional. I've not removed it because I don't know what it was supposed to point to. Whoever knows may fix it. 74.128.201.242 (talk) 04:19, 23 December 2009 (UTC)[reply]

Homeostasis in the freezer???

Re "...allows local homeostasis of humidity...", homeostasis usually refers to processes in a living organism. Equilibrium might be a better term. here.--agr (talk) 22:47, 4 April 2012 (UTC)[reply]

correcting for freezer burn

I don't know if this belongs to this article but feel free to insert it wherever you feel necessary.

I found that using a pressure cooker removes the effects of a freezer burned piece of meat in multiple ways. first and foremost, it replaces the lost water by inserting steam into the food. Second, it tenderizes the whole cut of meat (natural process of pressure cooking). Third, the meat flavors mix throughout the meat in the cooker and it all tastes just fine.

the ice cube controversy thing is you lose 1 inch of ice every 2 years (depending on the type of freezer)

External links modified

Hello fellow Wikipedians,

I have just added archive links to one external link on Freezer burn. Please take a moment to review my edit. You may add {{cbignore}} after the link to keep me from modifying it, if I keep adding bad data, but formatting bugs should be reported instead. Alternatively, you can add {{nobots|deny=InternetArchiveBot}} to keep me off the page altogether, but should be used as a last resort. I made the following changes:

Farenheit

I can't believe we are still putting Farenheit first and the C in brackets in 2024. The English Language Wikipedia is SO US- centric and it looks SO archaic (but I wouldn't dream of changing it, I assume its a US-written article- one day, you might do it yourselves ;) ).
