Specific volumes of chlorodifluoromethane in the temperature range from (298 to 573) K and pressures up to 500 MPa
The specific volumes of chlorodifluoromethane have been measured up to 500 MPa at eight isotherms ranging from (298.2 to 573.2) K. Experiments were performed with a thin-walled sample holder with equal pressure inside and outside. The volume change of the sample was determined with a separation system at 298.2 K by making use of a magnetic float on mercury and a linear variable differential transformer. The specific volume of chlorodifluoromethane varies in this region from (0.579 to 4.957) cm(3)center dot g(-1). The experimental uncertainty in specific volumes was estimated to be no greater than +/- 0.4 %. The Tait equation was used to correlate the data.
