Altered Image

Although the image was clear in explaining the topic, I considered the flames a little childish for an encyclopædia so removed them. --Shastrix 20:11, 22 February 2006 (UTC)- help u[reply]

Please do not merge these separate 6 pages

The merge debate goes back to '05 (see: Talk:Endergonic). The result of the debate was to not merge. Moreover, it is standard protocol, e.g. according to both The Essential Dictionary of Science (Clark 2004) and the A to Z Dictionary of Thermodynamics (Perrot 1998), to have separate entries for such closely-related but subtly-different topics such as:

Exothermic – a process or reaction that involves the release of energy; usually in the form of heat.
Exothermic reaction – a chemical reaction in which heat is give out.

As well as for the other terms: endothermic, endothermic reaction, etc. For example, the melting of an ice-cube is an endothermic process; combustion evolves an exothermic reaction, warm-blooded animals are endothermic, arguing with other Wikipedians is an endergonic activity, etc. Help us expand on these separate stubs, but please don't merge. Wikipedia has unlimited storage space. Articles are sure to grow. Thanks:--Sadi Carnot 17:30, 22 March 2006 (UTC)[reply]

Reference to Passive fire protection

Testing of endothermic materials for fire protection purposes goes back to the late 1800's and continues today. Clever chemists of conventional PFP materials are often motivated to sex the maximum hydrate contents into their products. The success of this methodology is plain to see, when one regards temperature ratings achieved by firestop mortars, compared against materials that are merely good insulators. The discussion of PFP and its constituents naturally leads to the term endothermic, which is why I believed the cross-reference was in order.--Achim 04:06, 20 April 2006 (UTC)[reply]

With regards to one of my edits: not all heatshields are necessarily ablative in nature and not all heatshields are used in space physics. Some are used for personnel comfort for instance in certain smelting operations.--Achim 02:09, 11 May 2006 (UTC)[reply]

Cooling packs

Are chemical "ice packs" (The type where you crush a seal inside of the package to get the substance in the package cold) examples of endothermic reactions?--RLent (talk) 14:48, 15 April 2008 (UTC)[reply]
