The following table lists the van der Waals constants (from the van der Waals equation) for a number of common gases and volatile liquids.
Units:
- 1 J·m3/mol2 = 1 m6·Pa/mol2 = 10 L2·bar/mol2
- 1 L2atm/mol2 = 101 325 J·m3/kmol2 = 101 325 Pa·m6/kmol2
- 1 dm3/mol = 1 L/mol = 1 m3/kmol (where kmol is kilomoles = 1000 moles)

Famous quotes containing the words van and/or der:
“My position is a naturalistic one; I see philosophy not as an a priori propaedeutic or groundwork for science, but as continuous with science. I see philosophy and science as in the same boat—a boat which, to revert to Neurath’s figure as I so often do, we can rebuild only at sea while staying afloat in it. There is no external vantage point, no first philosophy.”
—Willard Van Orman Quine (b. 1908)
“Under the lindens on the heather,
There was our double resting-place.”
—Walther Von Der Vogelweide (1170?–1230?)
