- What is the difference between vapour and gas?
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
- physical chemistry - Relationship between vapour pressure and saturated . . .
The saturated vapor pressure will be the vapor pressure of a closed system containing liquid and vapor in equilibrium It will change with the temperature of the system
- evaporation - What is the difference between smell odor and vapor . . .
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 By condensing the vapor, you can obtain the same stuff in liquid or solid form Smell on the other hand is a human animal perception
- physical chemistry - What is the differences between partial pressure . . .
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
- whats the difference between gas and vapour? [duplicate]
A vapor is a gas in possible equilibrium with its liquid [or solid] at a temperature below its critical T and either in contact with the liquid or at the equilibrium vapor pressure If not at a sufficient pressure to condense and not in contact with the liquid the vapor behaves as a gas [nonideal] and the term becomes colloquial
- Why does the pressure sharply increase when the liquid vapor . . .
The correct answer here is B, which I don't exactly understand I understand that the system being a mixture of vapor and liquid at low temperature makes sense, since as the temperature is raised, the vapor pressure of the liquid increases, and the vapor (which there is now more of) exerts more pressure in accordance with the ideal gas law
- General rules for deciding volatility - Chemistry Stack Exchange
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
- thermodynamics - Why do we have water vapor at room temperature and . . .
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 closed system The molecules in vapor form create a specific vapor pressure at a given temperature, as explained by the kinetic theory of gases
