• In the presence of MoF/sub 6/(g) which was added to suppress disproportionation, the vapor density of MoF/sub 5/ over the liquid was measured by the transpiration method at 343, 363, and 383 K, the total MoF/sub 5/ that evaporated being determined by permanganate titration. (osti.gov)
  • misc{etde_5309429, title = {Melting temperature, vapor density, and vapor pressure of molybdenum pentafluoride} author = {Krause, Jr, R F, and Douglas, T B} abstractNote = {A sample of MoF/sub 5/ was prepared by reaction of MoF/sub 6/(g) and Mo(c). (osti.gov)
  • Vapor pressure deficit can be a little difficult to comprehend at first, since most of us are already familiar with RH percentages and ideal levels for a greenhouse or indoor garden. (maximumyield.com)
  • Vapor pressure deficit is the difference between the amount of moisture currently in the air and how much moisture the air could hold when it is fully saturated. (maximumyield.com)
  • Stomatal responses to changes in vapor pressure deficit ( VPD ) constitute the predominant form of daytime gas-exchange regulation in plants. (plantphysiol.org)
  • In support of this, the dynamic responses of stomata throughout the day to changes in humidity, or more precisely the vapor pressure deficit between the leaf and the atmosphere ( VPD ), appear to be driven by subtle yet functionally relevant changes in foliar ABA level in angiosperms ( McAdam and Brodribb, 2015 ).

  • Thodos,2 in a careful survey of empirical vapor pres- seen that the reverse curvature of the 10gP versus liT sures of saturated hydrocarbons, has shown that the plot then corresponds to Cox's A going through a plot of 10gP versus liT is not quite linear but really mlmmum. (scribd.com)
  • High levels of vaporization are desirable for winter starting and operation and lower levels are desirable in avoiding vapor lock during summer heat. (wikipedia.org)
  • T, absolute temperature) may be explained on the basis of the nonideal behavior of the vapor together with the change in heat of vaporization with temperature. (scribd.com)
  • As the kinetic energy of the molecules increases, the number of molecules transitioning into a vapor also increases, thereby increasing the vapor pressure. (wikipedia.org)
  • 1. If an aqueous solution that is 0.15 M in HF has an osmotic pressure of 3.9 atm at 25oC, what is the percent ionization of HF at this concentration? (jiskha.com)
  • Vapor Pressure (VP) and concentration of chemicals above saturated aqueous solutions (C-air,), interconnected by Henry's law, are important properties with significant effects on the transport and partitioning of chemicals among environmental compartments. (eurekamag.com)
  • Effect of iodine-doping in the deposition solution and iodine vapor pressure during the sensitization process on the morphological, microstructural, electrical, and optical properties of PbSe films was studied. (spiedigitallibrary.org)
  • Very few studies have commented on the trigger for this more subtle increase in ABA level that occurs in dehydrated leaves at positive turgor pressures, yet these increases may be very important for the regulation of stomatal aperture in well-watered plants. (plantphysiol.org)
  • Using a novel method of modifying leaf cell turgor by the application of external pressures, we test whether changes in turgor pressure can trigger increases in foliar ABA levels over 20 min, a period of time most relevant to the stomatal response to VPD . (plantphysiol.org)
  • Very low vapor pressures of solids can be measured using the Knudsen effusion cell method. (wikipedia.org)
  • 1.2 This test method may be used for the temperature range 273 to 773 K (0 to 500°C) and for pressures between 0.2 kPa to 2 MPa. (astm.org)
  • Because a range of applied pressures is required by this test method, the analyst is best served by use of instrumentation referred to as high pressure differential thermal instrumentation (HPDSC or HPDTA). (astm.org)
  • A method for measuring the vapor pressures of a wide range of materials using a conventional thermobalance and standard sample holders is described. (sump4.com)
