This article is pretty pathetic. 65.167.146.130 (talk) 18:11, 12 January 2009 (UTC) its cold in here —Preceding unsigned comment added by 71.123.225.44 (talk) 13:48, 31 January 2009 (UTC)[reply]

I think the addition of the waiting room was funny. --67.153.136.131 (talk) 04:47, 1 March 2009 (UTC)[reply]

Nice, interesting and extensible! Why dissolve it within another article? 79.200.67.162 (talk) 12:56, 4 February 2009 (UTC)[reply]

I agree with the first user above. This article doesn't really say anything, especially of an encyclopedic caliber... Stevenmitchell (talk) 04:43, 4 March 2009 (UTC)[reply]

I'm just a non-physicist Dutch speaking guy, but ehm, why does it say that cooling of an object by exposure to ice, dry ice, or liquid nitrogen is done by convection? I'm thinking thermal conductivity, and if done in a fluid or gas (not ice!) convection might just occur, right? I hope some natively English speaking lab guy picks this part up.

Absolute Zero Theoretically Possible?

I don't know much about thermodynamics, but I am fairly certain that absolute zero is theoretically impossible. Am I right about this? If I am then the article should be changed to reflect that. Eiad77 (talk) 08:08, 12 July 2010 (UTC)[reply]

I don't see why it would be theoretically impossible. They've gotten close, see Bose–Einstein condensate. The problem is how you verify without heating. 75.15.202.83 (talk) 18:44, 24 December 2010 (UTC)[reply]

Opposite of hot?

Not really the scientific opposite of "hot," but rather the absence of heat. May be grammatically true, but this is not Wiktionary, but an encyclopedia. As pointed out above, while an absolute lack of heat cannot be achieved, we know where that is. We don't really know how hot it can get. Student7 (talk) 02:54, 24 December 2010 (UTC)[reply]

Cold and Hot are also touch senses, and in that sense are opposites. Presumably ice is cold whereas steam is hot to the touch. 75.15.202.83 (talk) 18:58, 24 December 2010 (UTC)[reply]
