How do the molecules absorb this extra energy? doesnt the temperature increase take account of the kinetic energy increase? does it break intermolecular bonds? help

There is another article - Latent heat of fusion - with more or less the same content. It might be a good idea to unify the two. --Peterlin 09:47, 16 Jun 2004 (UTC)

done.

I think it might be good to put the heat of fusion of some common substances such as water, steel, copper, various salts. A small table like this could be found in most high school chemistry textbooks. --Baltakatei 22:45, 11 Jan 2005 (UTC)

The article currently claims to change states from a solid to a liquid or vice versa. ... the temperature at which it occurs is called the melting point.

Yes, that's what normally happens, but what about supercooling heat pads ? When you diddle with them and they warm themselves up, that warmth comes directly from the heat of fusion, right ? But "the" temperature it occurs at (both the cold room temperature and the maximum "warm" temperature it it gets to as it crystallizes) -- they're both well below the (hot!) normal melting point, right ? Would adding another "application" involving a sodium acetate heat pad be a good idea, or just confusing? (What is the heat of fusion of sodium acetate?) --DavidCary 12:54, 22 September 2005 (UTC)

Latent heat

Heat of solution

Heat of Formation

This used to be called Heat of Formation. It would be nice if a link for that existed and directed here. Also if some discussion of the history of it was briefly done.

The symbol for fusion

The symbol for the heat of fusion should be in here somewhere no? $\Delta {}_{fus}H$ ?

Solubility prediction

In response to the edit by User 141.224.143.192: This segment is written down as part of the Wikipedia:Chemistry Collaboration of the Month: Solubility. The topic can be found in many physical chemistry textbooks and I think it is relevant. See also Wikipedia:Scientific citation guidelines. Hope this answer helps. V8rik 18:23, 25 January 2007 (UTC)
