== What does "rest heat" mean? ==
Paul, in the "Discussion of the second law" section, you refer to Q<sub>c</sub> as the "rest heat". Did you mean "heat at rest" or did you mean "the rest of the heat" or the "remaining heat"? I made no changes, but I do think that if you meant "remaining heat", then the wording needs to be changed. Perhaps to "remainder heat"?
If, on the other hand, you really meant "heat at rest", then the wording also needs to be changed, because "rest heat" need to be clarified as to what is meant. [[User:Milton Beychok|Milton Beychok]] 19:58, 6 November 2009 (UTC)

What does "rest heat" mean?

Paul, in the "Discussion of the second law" section, you refer to Qc as the "rest heat". Did you mean "heat at rest" or did you mean "the rest of the heat" or the "remaining heat"? I made no changes, but I do think that if you meant "remaining heat", then the wording needs to be changed. Perhaps to "remainder heat"?

If, on the other hand, you really meant "heat at rest", then the wording also needs to be changed, because "rest heat" need to be clarified as to what is meant. Milton Beychok 19:58, 6 November 2009 (UTC)
