To find the volume, which a given volume under standard conditions would
assume, if those conditions are altered.

Volume ◊ 2.784 ◊ (Temperature + 273)
Resulting volume = ------------------------------------
Pressure - tension

As an example, we will suppose that it is desired to enclose in the
apparatus referred to on p. 45, a volume of air, which, when dry (at 0∞
C. and 760 mm.), shall measure 100 c.c., whilst the actual temperature
is 15∞ C., and the pressure 750 mm.

The second formula is the one to be used, and we get 108.7 c.c.

100 c.c.◊2.784◊288
Required volume = ----------------------
750-12.7
