The table below gives thermodynamic data of liquid CO2 in equilibrium with its vapor at various temperatures. Heat content data, heat of vaporization, and entropy values are relative to the liquid state at 0 °C temperature and 3483 kPa pressure. To convert heat values to joules per mole values, multiply by 44.095 g/mol. To convert densities to moles per liter, multiply by 22.678 cm mol/(L·g). Data obtained from CRC Handbook of Chemistry and Physics, 44th ed. pages 2560–2… WebThe Refractive Index - n - of a medium is a measure for how much the velocity of light is reduced inside the medium. The velocity of light in a medium can be expressed as v = c / …
WebIn this work, the four as-prepared ChCl: saccharides were evaluated at varying mass percentages of water, 0, 10, 20, and 30 wt.%. Physical properties were analyzed, including pH, which tended to be neutral, conductivity, and refractive index, which was about 1.5 nD for the ChCl: saccharide NADES prepared at different conditions. The refractive index is an important property of the components of any optical instrument. It determines the focusing power of lenses, the dispersive power of prisms, the reflectivity of lens coatings, and the light-guiding nature of optical fiber. Since the refractive index is a fundamental physical property of a substance, it is often used to identify a particular substance, confirm its purity, or measure its concentration. The refractive index is used to measure solids, liquids, and …
WebFigures 2.3.8 and 2.3.9 show the relationship between the molecular weight of a solvent and its refractive index. Figure 2.3.8 shows that there is a general tendency for the refractive index to increase as the molecular weight of the solvent increases. The data also indicates that there must be an additional factor governing refractive index. The chemical structure … WebRefractive index database Shelf. Book Page.

WebJan 1, 2006 · The refractive index of carbon-dioxide, nitrogen, helium, oxygen and air have been measured at 23 °C temperature by means of a tunable CO 2 laser at 10.57 μm and of a differential interferometric technique. As the gas refractive index depends on the pressure P as n = 1 + α P P, the pressure coefficients α P has been measured with 5e–3 accuracy.
