Pressure and Temperature Dependence of Liquid Density


pressure and TemperaTure dependence of liquid densiTy
This table gives data on the variation of the density of some common liquids with pressure and temperature . The pressure dependence

is described to first order by the isothermal compressibility coefficient κ defined as κ = -(1/V) (?V/?P)T where V is the volume, and the temperature dependence by the cubic expansion coefficient α, α = (1/V) (?V/?T)P Substances are listed by molecular formula in the Hill order . More precise data on the variation of density with temperature over a wide temperature range can be found in Reference 1 .
Molecular formula Cl3P H2O Hg CCl4 CHBr3 CHCl3 CH2Br2 CH2Cl2 CH3I CH4O CS2 C2Cl4 C2HCl3 C2H2Cl2 C2H4Cl2 C2H4Cl2 C2H4O2 C2H5Br C2H5I C2H6O C2H6O2 C3H6O C3H7Br C3H7Cl C3H7I C3H8O C3H8O C3H8O2 C3H8O2 C3H8O3 C4H8O2 Name Phosphorus trichloride Water
