I believe you mean the temperature at which water vapor condenses due to cooling. This is the dew point temperature.

When a liquid and its vapor are at equilibrium and pressure is suddenly decreased cooling occurs why?
Since the volume did not change, then a decrease in pressure has to change the temperature as well. The change in pressure decreased the kinetic motion and energy of the molecules, so the temperature correspondingly drops. This follows Gay-Lussac's Law where P1T2=P2T1
How does temperature affect vapor pressure?
Vapor pressure increases with temperature. As the temperature increases ,molecules of liquid find it easier to escape.
Why acetone have more cooling effect than water?
Acetone has a lower boiling pt. than water because it has a higher vapor pressure. Liquids boil at the temperature where their vapor pressure is equal to the atmoshperic pressure. The temperature that acetone must get to, such that its v.p. is equal to the pressure of the atmosphere, is lower than what is required for water. Therefore, acetone has a lower B.P.
How the boiling water and cooling of water vapor is a reversible reaction?
Unicorns
Heat which is added to a vapor after the change of state occurs is called?
Adding heat to a vapor after the change of state from liquid to vapor has occurred is called super-heating. For example, adding heat to steam at 100 C and 101.325 kPa is called super-heating.
Condensation of water vapor in the air occurs when the temperature drops below the point at which the air's?
capacity and specific humidity are the same
What can cause water vapor in the air to be cooled?
The process is called condensation. It occurs when the water is cooled below its boiling point due to the temperature in the environment cooling it.
What does water vapor need in order to change states from a gas to a liquid?
Water vapor needs to condense by cooling it.
When water vapor becomes liquid water due to cooling what is it?
condensation
The temperature at which the vapor pressure of a liquid is equal to the external pressure is the what?
The temperature at which the vapor pressure of a liquid is equal to the external pressure is the boiling point. Evaporation is when vaporization of an uncontained liquid occurs.
Why does precipitation occurs?
Precipitation in the water cycle occurs when water vapor condenses from the air and falls as water or ice. Normally this is caused by cooling either from an air mass or from a temperature drop at higher altitude. Precipitation in a chemical reaction occurs when chemical products are insoluble in a solution, or when the solution cannot hold the total volume of solutes present.
What difference in temperature is needed for condensation?
It varies for the condensing vapor and humidity. Condensation occurs when a vapor is cooled to its dewpoint. See "dew point" for more information. It is not necessarily a difference in temperature, since it changes based on humidity and air temperature.
Does dew come from rain?
Not exactly. Dew occurs when the air is saturated with water vapor and condensation occurs once a certain temperature is met.
When a liquid and its vapor are at equilibrium and pressure is suddenly decreased cooling occurs why?
Since the volume did not change, then a decrease in pressure has to change the temperature as well. The change in pressure decreased the kinetic motion and energy of the molecules, so the temperature correspondingly drops. This follows Gay-Lussac's Law where P1T2=P2T1
Cooling the air to a temperature below the dew point causes the water vapor to begin to change back into a liquid is what process?
Condensation
Why is cooling always cause evaporation?
Cooling does not cause evaporation. Warming does. This is because as the air warms up, there's more space for water vapor in it. Water evaporates and turns into water vapor to fill this space.
What occurs during condensation?
Condensation occurs in the atmosphere as part of the phases in rain cycle. During the condensation phase, water vapor transforms into liquid form. When warm air rises into the atmosphere, it cools down and loses its ability to hold water vapor resulting to the condensation of water forming cloud droplets.
