The vapour pressure of a solvent in a solution is lower than that of pure solvent, at the same temperature. A higher temperature is needed to raise the vapour pressure up to the atmospheric pressure, when boiling begins. However, increase is small, like0.1molkg−1aqueous sucrose solution ...
P = X(A) P^(@):If P^(@) the vapour pressure of a pure solvent and P is the vapour pressure of the solution prepared by dissolving a non volatile solute in it. The mole fraction of the solvent X(A) is given by:
Raoult’s Law relates the vapour pressure of the solvent above the solution to its mole fraction in the solution. Which of the following is an accurate statement?A.Raoult’s Law applies exactly to all solutions.B.Raoult’s Law works best when applied to

The Solubility and Isotopic Fractionation of Gases in Dilute Aqueous Solution. IIa. Solubilities of the Noble Gases A method for the analysis of precise gas solubility data is presented and applied to new determinations of the Henry constant, k 2 , for He, Ne, Ar, Kr, an... D Krause,BB...
By the use of a specifically shaped new CS2 elevator, the membrane elevation can be also performed in cases where the bone is insufficiently mineralized and watertightness is not perfect, with consequent leakage of the physiological solution; a great support for the operator and a higher guarantee...
Orogenic peridotites in the crystalline basement of the northwestern Bohemian Massif contain multiphase solid inclusions (MSI), which are interpreted to be crystallisation products of trapped former carbonate–silicate melts metasomatizing their host rocks. We applied conventional thermobarometry and forward ...
The thermoregulatory implications of evaporating nectar before return to the hive are unknown: the associated evaporative heat loss will depend on vapour pressure deficits during foraging and may or may not be an advantage to individual foragers24,29. Our findings cast some doubt on crop volumes ...
Precise time-resolved measurements of the particle radius allow us to elucidate the microphysical factors influencing water partitioning over a range of temperatures (248 - 330 K) and relative humidities (0 - 95 %). Specifically, we explore the vapour pressure of pure water in supercooled ...
The vapour pressure at a given temperature of an ideal solution containing 0.2mol of non-volatile solute and 0.8mol of a solvent is 60mm of Hg. The vapour pressure of the pure solvent at the same temperature will be A150 mm of Hg B60mm of Hg C75 mm of Hg D120 mm of HgSubmit An ...
