I like this terminology. Where does it come from? —Preceding unsigned comment added by 65.43.126.224 (talk) 00:47, 12 January 2006 (UTC)[reply]

This version of the article says "A property can be identified as a process (or path) function if it is in lower case." That doesn't seem right. For instance heat is a process function but I've always seen it denoted in the uppercase: ${\displaystyle Q}$. The only time I've seen it in lower case is as a unit quantity (heat per area: ${\displaystyle q}$). I have removed the sentence. Riick (talk) 00:40, 24 August 2010 (UTC)[reply]

"It depends on the heat done ": that doesn't make sense either. DS Belgium (talk) 12:20, 25 October 2011 (UTC)[reply]

Last paragraph says:

<<Path functions depend on the path taken to reach one state from another. Different routes give different quantities. Examples of path functions include work, heat, and distance. In contrast to path functions, state functions are independent of the path taken.>>

Distance, being defined as the length of the shortest path between to points, is independent of path by definition. The article should talk instead about 'length'. I'm going to change it.

Can this article be renamed to Path function, which is the usual terminology in physical chemistry textbooks? We could still mention Process function as a synonym in the article. But the use of Process function as the article name invites confusion with the engineering term Process variable, which apparently includes state functions such as temperature and pressure!

It is p-function, where p can refer to either process or path. 77.83.254.178 (talk) 07:12, 29 February 2024 (UTC)[reply]
