- 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
- What is the differences between partial pressure and vapour 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
- 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 pressure for oxygen, and the sum of the two partial pressure is the actual pressure (the absolute pressure)
- 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
- How to calculate the composition of an ideal binary solution when only . . .
The only part with which I'm having a problem is the part when vapor pressure of each compound in its pure state is given along with how much amount of each compound is mixed together, I have to find the composition of the compounds in the solution phase after a certain part of the solution has turned into vapor and have achieved an ideal state
