-
Once equilibrium is reached between a vapor and a liquid, what does this mean for the pressure exerted by the vapor over the liquid?
It remains constant
-
What is the pressure of vapor in equilibrium with a liquid called?
Vapor Pressure
-
If both liquid and vapor are present, will the pressure exerted by the vapor be dependent on the container's volume?
No
-
State the Clausius-Clapeyron equation
ln(P2 / P1) = (deltaHvap / R)*[(1/T1) - (1/T2)]
-
Scientifically; when does a liquid boil?
When it reaches a temperature where its internal vapor pressure is equal to the pressure above its surface.
-
What is the critical temperature?
This is the temperature value above which the liquid phase of a substance cannot exist
-
What is critical pressure?
This is simply the vapor pressure of a liquid at its critical temperature.
-
What is a supercritical fluid?
This a substance above its critical temperature and pressure.
-
What is the triple point of a substance?
This is the temperature and pressure at which all three phases of a substance are in equilibrium.
-
What is sublimation?
The process by which a solid changes directly to a vapor.
-
At what temperatures can a solid sublime?
Only temperatures below the substance's triple point.
