The relative humidity is a ratio of the amount of water in a given air over the amount of water that could be held in that same parcel of air. This number will vary as the temperature rises and falls as warmer air can hold more water than cooler air.

What is difference between rain and dew?
rain falls while dew drizzles.
Temperature to which air must be cooled to reach saturation?
The temperature to which air must be cooled to reach saturation is called the dew point.
Is dew an example of condensation?
No, dew is thick, most of the time. Examples of condensation include; Heat on a cold window, or mist.
Difference between dew point and boiling point?
Boiling point is the temperature(at a particular pressure) of a pure substance at which it boils . e.g water at 1 atm will boil at 100 degreeC. If u start heating water its temperature will rise from ambient to 100 degC only until it totally boils to steam. For a mixture of two components there will not be a single b.p. During boiling its temp will rise so the mixture will have an initial b.p and a final b.p. For a pure component you only have boiling point, if u cool steam from say 120 degC, water will condense out at 100 degC. If you cool air which contains water which we call water vap or moisture, the water will condense at a particular temp which we call as dew point. This temp will depend on the amount of water vap in the air.
Does transpiration effect dew on grass?
Absolutely. Air which is close to the ground cools overnight. While the air is cooling, the relative humidity is increasing until it reaches the dew point and water is released. Transpiration can also cause the dew point to be reached by increasing the relative humidity. This is why there is much more dew on the grass than on pavement.
Which weather change usually occurs when the difference between the air temperature and the dew point temperature is decreasing?
probability precipitation decrease
When a parcel of air reaches its dew point what process begins?
Some sort of precipitation occurs when air reaches the dew point. You might get dew, frost, rain or snow.
Is dew and frost caused by precipitation?
No, precipitation is a separate process. Dew and frost occur when air cools to its dew point. Dew is condensation of water in the air onto a surface, while frost is the deposition of water vapor straight to ice.
Dew point is 10C temperature falls to 12C at night?
there will be no precipitation in the morning
What is the difference between relative humidity and dew point temperature?
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.
How is dew point different from condensation?
the realationship between condensation and dew point is that condensation occurs when it reaches the dew point.
What type of humidity is a pyschrometer used for?
It is used to find the dew point of the atmosphere. At which point the water has to come out, as precipitation.
What two types of precipitation can occur if the dew point is below zero degrees Celsius?
Frost.
What is a form of precipitation?
Dew
When the ground has enough moisture and the temperature reaches the dew point what happens?
When the temperature comes down to the dew point, the air can support no more water vapour and the dew begins to to form. Air can absorb more water vapour as the temperature rises, so the difference between the dew point and the actual temperature gives a measure of the humidity.
What is difference between rain and dew?
rain falls while dew drizzles.
What is the relationship between the temperature and 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.
