sublimation pressure การใช้

• The indicator of volatility is saturated vapor pressure ( sublimation pressure ).
• It gives a model for the sublimation pressure ( as a function of temperature ) for the range 154-196 kelvin.
• There are a number of methods for calculating the sublimation pressure ( i . e ., the vapor pressure ) of a solid.
• It also shows that the sublimation pressure is lower than the extrapolated liquid vapor pressure ( ? " H " m is positive ) and the difference grows with increased distance from the melting point.
• One method is to estimate the sublimation pressure from extrapolated liquid vapor pressures ( of the supercooled liquid ), if the heat of fusion is known, by using this particular form of the Clausius Clapeyron relation:
• It's notable that observed concentration of methane is 2 orders of magnitude higher than expected from Raoult's law on the basis of its concentration in surface ice and ratio of sublimation pressures of methane and nitrogen.
