A computer program for calculating van der Waals volume

A Computer Program for Calculating van der Waals Volume A computer program, written in Fortran IV, has been developed that allows for an iterative process that converges to the true volume of s gas that obeys van der Waals equation. This oromam is reedilv rtdmtable to remote terminal use. ma; he utilized to show variations in volume with temperature nt consrnnt The preswre (Ch~rlcsLaw) and to *how varintiong in volume with pressure at ron*tant temperature (Doyle's l.nw, for an idealaas and iora van der Wanlsgas. The valws foro and (I for n particular gas are found in standard physical chemistry texts.' A copy of the program is available from the author on request. 7~
