No, not in general - only under specially created conditions
Yes.
The dew point is a measure of the amount of water vapor in the atmosphere. As the temperature gets closer to the dew point, the humidity rises. When the temperature finally drops to the dew point (100% humidity), the the atmosphere is completely saturated with water, and it will start to rain (or snow, if the dew point is below freezing). Since the atmosphere is completely saturated when the temperature is at the dew point, it cannot go below the dew point.
Dew point is the temperature at which the water vapor in the air condenses, then evaporates. The barometric or air pressure is independent from the dew point.
Dew Point: Is the temperature at which gas condenses into a liquid.
The Dew Point.
Cooling air below the dew point will result in the water in that air coming out of solution to deposit itself on surfaces. We call that dew. Certainly as the temperature continues to fall, it may even cause rain (if it isn't too cold).
The Dew Point is the temperature at which the air is at 100% Relative Humidity. If the temperature fall below the Dew Point, then there is more moisture in the air than it can hold, and water condenses in the form of dew, mist, rain, etc.
Dew point is supposed to be the temperature that water vapor is cooled to. If the air is colder than the condensation point (dew point) then it isn't being cooled.

The reason frost forms on windows is due to the dew point and temperatures. The dew point is a temperature at which water in the air will condense into liquid H2O. In this case the H2O has reached the dew point and has actually frozen due to reaching a temperature of or less than 32 degrees Fahrenheit.
The temperature to which air must be cooled to reach saturation is called the dew point.
The temperature in which air is saturated and condensation can occur is the "dew point." It has no specific temperature but it occurs when the air is saturated. The air is saturated when it has a relative humidity of 100 percent, or if i cools down to its dew point.
The approximate dew point at sea level is dependent on more than just the sea level itself. Calculating dew point requires the air temperature as well as relative humidity. So in a general sense, there is no difference in dew point based on elevation if the temperature is the same.
Dew point is the temperature at which air becomes saturated.
when the temperature reaches the dew point.
At temperatures below the dew point there is less evaporation than condensation. Drops and droplets condense and grow. At temperatures above the dew point there is more evaporation than condensation, drops and droplets evaporate.
The dew point controlled the temperature of the air.
Dew point is reached when the temperature is low.
