  1. What is the difference between "vapour" and "gas"?

    Apr 19, 2021 · Vapor implies the existence of a condensed phase that is the source or destination of the gas, or with which the gas may be in equilibrium; while gas does not make such an assumption.

  2. thermodynamics - Why do we have water vapor at room temperature …

    May 6, 2024 · 1 Think of molecules of water liquid escaping into vapor, and molecules of water vapor condensing into liquid. Both processes occur simultaneously, and an equilibrium is reached in a …

  3. Why does the pressure sharply increase when the liquid/vapor ...

    Oct 2, 2024 · The equilibrium vapor pressure varies with temperature because of two factors - 1)kinetic energy of particles and 2) number density. Both increase non-negligibly with temperature. The …

  4. physical chemistry - What is the differences between partial pressure ...

    Jan 23, 2014 · Vapor pressure or equilibrium vapor pressure is the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases (solid or liquid) at a given temperature in a …

  5. Relationship between vapour pressure and saturated vapour pressure

    Aug 5, 2015 · I need clarity on saturated vapour pressure in a closed system at equilibrium. How does saturated vapour pressure relate to vapour pressure?

  6. thermodynamics - Does the term "vapor pressure" even mean …

    Sep 25, 2023 · The partial pressure of vapor is approximately equal to (saturated) vapor pressure and the pressure difference to external pressure is compensated by partial pressure of the system air. If …

  7. Confusion between vapor pressure vs. vapor-liquid equilibrium

    Sep 22, 2024 · At the right low gas pressure means no liquid; increasing pressure below the critical T eventually induces liquid formation in equilibrium; attempts to increase pressure simply increase …

  8. Why is the relationship between vapour pressure and boiling point of ...

    Dec 26, 2023 · 3 If you took out vapor at some moment and if you put it in a container of a fixed volume then its pressure would linearly grow with temperature, as in the Charles' law. The point is, amount of …

  9. Vapor Pressure of Two Immiscible Liquids [duplicate]

    Apr 23, 2024 · While the concept of vapor pressure applies similarly to both immiscible and miscible liquids, there are important distinctions between the behavior of these two types of mixtures when it …

  10. vapor pressure - What is the difference between volatility and ...

    A measure of volatility is the vapor pressure. There is a very related term partial pressure. So if we think of air as being nitrogen and oxygen, then there is a partial pressure for nitrogen and a partial …
