- 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 . . .
I need clarity on saturated vapour pressure in a closed system at equilibrium How does saturated vapour pressure relate to vapour pressure?
- whats the difference between gas and vapour? [duplicate]
Wikipedia: Vapor In physics, a vapor (US) or vapour (UK, CA) is a substance in the gas phase at a temperature lower than its critical temperature, which means that the vapor can be condensed to a liquid by increasing the pressure on it without reducing the temperature
- 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
- Why does the vapour pressure not depend on the surface area and volume . . .
I think that you forget about molecules re-entering the liquid from the vapour Eventually the vapour will come into equilibrium with its liquid and so the rate of leaving the liquid and the rate of colliding with the liquid surface and so re-entering, become equal When this happens the vapour pressure becomes constant
- 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 arrange substances in order of increasing vapor pressure?
In Raoult's law, the vapor pressure of a fluid is lowered proportionally with the mole fraction of solute particles in the fluid You know the formula, but you only need it if you want to calculate the actual resulting vapor pressure
- physical chemistry - Why is octane more volatile than water while . . .
14 Octane has a boiling point of 120 °C Water has a boiling point of 100 °C The definition of boiling point is, "the temperature which the liquid substance's saturated vapor pressure equals the atmospheric pressure" Volatile substances have higher saturated vapor pressure at a given temperature, than the lesser volatile substances
