Yes. Below the freezing point the relative humidity will indicate how close the moisture in the air is to depositing and forming frost or snow.
The dew point is the varying temperature at which atmospheric humidity condenses. If the air temperature drops below the dew point, dew and condensation form.
The relative humidity percentage wil continue to rise until the dew point is achieved (100% relative humidity). This is when the proper pressure conditions are correct for the water particles in the air to accumulate causing the effect most know as "morning dew".
Relative humidity is reported in percentages. The percentage relates to the amount of water vapor air of a given temperature holds when it is saturated. So the humidity is reported as 50%, if the amount of water vapor in the air is half of what the air could hold at its current temperature.
The condensation of water from air (dew point) depends on temperature, pressure and the relative humidity of the air. It is not a single point for all conditions. For a specific set of conditions this data may be determined from a Psychrometric chart
Water will start to condense onto objects when the air becomes "saturated" - when the temperature drops to the dew point (at which point the relative humidity will be 100%).
It stays at 100%.
When the relative humidity and dew point temperature are the same they form clouds.

It is 100%.
It is 100%.
relative humidity is the AMOUNT of water in the air. Dew Point is the TEMPERATURE at which the water vapor in the air is turned into liquid water.
Relative humidity expresses a percentage of humidity in the air to the maximum amount of humidity that could be in the air. For example: when the temperature rises the air will be able to hold much more humidity so the relative humidity will drop.
When the air temperature reaches the dew point, water droplets that are in the air become visible. This is how you would get fog. Relative Humidity goes soaring to near 100%.
Yes.
Yes. Below the freezing point the relative humidity will indicate how close the moisture in the air is to depositing and forming frost or snow.
The dew point is the temperature at which a given parcel of humid air must be cooled, at constant barometric pressure, for water vapor to condense into water. The condensed water is called dew. The dew point is a saturation temperature.The dew point is associated with relative humidity. A high relative-humidity indicates that the dew point is closer to the current air temperature. Relative humidity of 100% indicates the dew point is equal to the current temperature and the air is maximally saturated with water. When the dew point remains constant and temperature increases, relative humidity will decreaseTherefore, by the above stated reasons (of humidity and barometric pressure and saturation based on temperature) are all reasons the point at wick dew forms is not the same because the regions them selves vary and thus these relative factors maybe dissimilar.
