The quantity of caloric disengaged by the
combustion of one pound of phosphorus, expressed
by the number of pounds of ice melted
during that operation, is 100.00000.
The quantity disengaged from each pound of
oxygen, during the combustion of phosphorus,
expressed in the same manner, is 66.66667.
The quantity disengaged during the formation
of one pound of phosphoric acid, 40.00000.
The quantity remaining in each pound of phosphoric
acid, 0.00000(A).
[Note A: We here suppose the phosphoric acid not to contain any caloric,
which is not strictly true; but, as I have before observed, the quantity
it really contains is probably very small, and we have not given it a
value, for want of a sufficient data to go upon.--A.]
_Combustion of Charcoal._
In the combustion of one pound of charcoal, 2 libs. 9 oz. 1 gros
10 grs. of oxygen gas are absorbed, and 3 libs. 9 oz. 1 gros 10
grs. of carbonic acid gas are formed.
Caloric, disengaged daring the combustion
of one pound of charcoal, 96.50000(A).
Caloric disengaged during the combustion of
charcoal, from each pound of oxygen gas
absorbed, 37.52823.
Caloric disengaged during the formation of
one pound of carbonic acid gas, 27.02024.
Caloric retained by each pound of oxygen
after the combustion, 29.13844.
