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.
evaporation - What is the difference between "smell/odor" and "vapor ...
Nov 30, 2022 · 1 What is the difference between "smell/odor" and "vapor" of a substance? It is assumed that the vapor of a given compound/element is the gas phase of the same pure compound/element. …
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 …
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 …
Why do water and ice have the same vapor pressure at 0 °C?
Jan 19, 2025 · 5 The phase with higher vapor pressure would evaporate and condense as the other phase. That is why vapor pressure above both substance condensed phases must be equal at the …
Question about vapor pressure in solids and liquids
Jun 14, 2023 · I've been reading about vapor pressure and it's a bit confusing. For example when water is in equilibrium between the solid and liquid phase, my textbook says that the vapor pressure is …
What is the differences between partial pressure and vapour 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 …
In a perfect vacuum, shouldn't every solid be above its sublimation ...
Sep 30, 2024 · If the sublimation point of a substance is the point where its equilibrium vapor pressure exceeds the pressure of the atmosphere upon it, and if every solid above absolute zero has some …
thermodynamics - Does the term "vapor pressure" even mean …
Sep 25, 2023 · Consider, for example, water vapor at 95 C. Obviously, evaporation still occurs at the surface, but since its saturation vapor pressure is less than the surrounding atmospheric pressure, …
Is the vapor pressure of a liquid dependent on the pressure of the ...
Oct 20, 2019 · The figure below shows how vapor pressure of a liquid is measured. Initially the flask is at atmospheric pressure. Then the liquid is dropped in the flask. Once equilibrium is reached, the …
