The recent meaning of vapor from OED, "Vapor: In modern scientific use, a fluid that fills a space like a gas but, being below its critical temperature, can be liquefied by pressure alone." This is clear enough. Now apply this distinction to your phase diagram and notice the position of the critical point.
At room temperature and 1 atm pressure liquid water should be a compressed liquid. Now if that is the case then why do we have water vapor at these conditions? I can't make sense of this based on j...
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.
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 closed system.
In chemistry and physics, volatility is the tendency of a substance to vaporize. Volatility is directly related to a substance's vapor pressure. At a given temperature, a substance with higher vapor pressure vaporizes more readily than a substance with a lower vapor pressure. (Taken from Wikipedia) But this doesn't seem to work--I recall that methanol is less volatile than ethanol I think you ...
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 equal betwe...
By definition vapor pressure seems the pressure of vapor ABOVE the liquid which is in equilibrium with liquid and how the hell we are applying the concept of vapor pressure in open container while discussing boiling?
