When an object is cool and warm air touches the cool object, the air cools and droplets of water forms on the outside of the object.Relative humidity is a comparison between how much water is already in the air compared with how much water the air is able to hold at a certain temperature.Another large source of water vapor in the air is when the plants absorb water through their roots and stems into their leaves.Characteristics of water vapor include it being colorless, odorless, invisible, and has no taste.All of the water in the air, whether it is from the world's ocean and other bodies of water, the water on a mirror following a hot shower, or the water a plant releases into the air; it is all called humidity because it is the amount of water vapor in the air.When the air is filled with this water, the amount of water in the air can be measured.The air could be become foggy or misty, or dew may appear on the grass in the mornings.The molecules of the water is absorbed by the Sun's energy near the surface of the water which then evaporates into the air.The process of plants releasing water into the air is called transpiration.Another measurement used is called relative humidity.Examples include moisture on the outside of a cold glass, or a mirror after a hot shower, which is also called condensation.Humidity is the amount of water vapor in the air.Water vapor gets into the air day through the process of evaporation.In summary, the water in the air is called water vapor.Plants also release water into the air during a process called transpiration.Finally, all of the water vapor in the air is called humidity.A comparison between how much water is already in the air compared with how much water the air is able to hold at a certain temperature is called relative humidity.When this happens there could be rain, snow, fog, or dew.This water in the air is called water vapor.Water vapor is in the form of a gas.When the in the air turns into a gas it is called evaporation.Ocean water, and other bodies of water, is turned into water vapor using the energy from the sun.The changing of a gas into a liquid is called condensation.An example of condensation is the water which covers a mirror following a hot shower.When the air can no longer hold the water vapor several things can happen.It may rain or snow depending on the temperature.Another problem with too much water vapor in the air, especially in the summer, is it becomes very uncomfortable and people began to sweat very easily.Water vapor in the air forms when cold air and warm air come in contact with each other.When this water is turned into a gas and is released into the air it is called evaporation.This is the result of the hot and cold air coming into contact with each other.The leaves then give off water.

When an object is cool and warm air touches the cool object, the air cools and droplets of water forms on the outside of the object. This is the result of the hot and cold air coming into contact with each other. This water in the air is called water vapor. Water vapor is in the form of a gas. Characteristics of water vapor include it being
colorless, odorless, invisible, and has no taste. Humidity is the amount of water vapor in the air. When the in the air turns into a gas it is called evaporation. Water vapor gets into the air day through the process of evaporation. Ocean water, and other bodies of water, is turned into water vapor using the energy from the sun. The molecules of the water is
absorbed by the Sun's energy near the surface of the water which then evaporates into the air.
The changing of a gas into a liquid is called condensation. An example of condensation is the water which covers a mirror following a hot shower. Another large source of water vapor in the air is when the plants absorb water through their roots and stems into their leaves. The leaves then give off water. The process of plants releasing water into the air is called transpiration.
All of the water in the air, whether it is from the world's ocean and other bodies of water, the water
on a mirror following a hot shower, or the water a
plant releases into the air; it is all called humidity
because it is the amount of water vapor in the air.When the air is filled with this water, the amount of water in the air can be measured. Another measurement used is called relative
humidity. Relative humidity is a comparison between how much water is already in the air compared with how much water the air is able to hold at a certain temperature. When the air can no longer hold the water vapor several things can happen. It may rain or snow depending on the temperature. The air could be become foggy or misty, or dew may appear on the
grass in the mornings. Another problem with too
much water vapor in the air, especially in the
summer, is it becomes very uncomfortable and
people began to sweat very easily.
In summary, the water in the air is called water
vapor. Water vapor in the air forms when cold air and warm air come in contact with each other. Examples
include moisture on the outside of a cold glass, or a mirror after a hot shower, which is also called condensation. When this water is turned into a gas and is released into the air it is called evaporation. Plants also release water into the air during a process
called transpiration. Finally, all of the water vapor in the air is called humidity. A comparison between how much water is already in the air compared with how much water the air is able to hold at a certain
temperature is called relative humidity. When this happens there could be rain, snow, fog, or dew.
