Moisture in its gas state in air.

  Water in a vaporous form, especially when below boiling temperature and diffused (e.g., in the atmosphere).

molecules of liquid water suspended in the air.

(Also called aqueous vapor, moisture.) Water substance in vapor form; one of the most important of all constituents of the atmosphere. Its amount varies widely in space and time due to the great varie [..]

Water in gas phase

The most abundant greenhouse gas, it is the water present in the atmosphere in gaseous form. Water vapor is an important part of the natural greenhouse effect. While humans are not significantly increasing its concentration through direct emissions, it contributes to the enhanced greenhouse effect because the warming influence of greenhouse gases l [..]

The gas phase of water. Under normal atmospheric conditions, water vapor is continuously generated by evaporation and removed by condensation.

Moisture existing as a gas in air.

Water in its gaseous form.

 Water vapor is the primary gas responsible for the greenhouse effect. It is believed that increases in temperature caused by anthropogenic emissions of greenhouse gases will increase the amount of wa [..]

the gaseous state of water

The most abundant greenhouse gas, it is the water present in the atmosphere in gaseous form. Water vapor is an important part of the natural greenhouse effect. While humans are not significantly increasing its concentration, it contributes to the enhanced greenhouse effect because the warming influence of greenhouse gases leads to a positive water [..]

a synonym for steam, usually used to denote steam of low absolute pressure.

Water diffused as a gas in the atmosphere.

Water in the form of a vapor, especially when below the boiling point and diffused. (McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)

The most abundant greenhouse gas, it is the water present in the atmosphere in gaseous form. Water vapor is an important part of the natural greenhouse effect. While humans are not significantly incre [..]

Water in an invisible gaseous state or in a visible liquid state consisting of extremely small particles suspended in the air.

gaseous water (individual water molecules) in the atmosphere. Watt

Water present in the atmosphere in gaseous form; the source of all forms of condensation and precipitation. Water vapor, clouds, and carbon dioxide are the main atmospheric components in the exchange [..]

Water in the invisible gaseous form.

The most important greenhouse gas, even ahead of carbon dioxide. Without water vapor from natural sources, the Earth's surface would be around 22 degrees Celsius cooler. This makes water vapor responsible for two-thirds of the natural greenhouse effect (33 degrees Celsius). For each kilo of kerosene burned, 1.24 kilos of water vapor are releas [..]

  Water in the form of gas. Water vapor is transported by air movement caused by pressure differences.

Water present as a gas in the atmosphere.

Water in a vapor (gaseous) form; also refered to as atomospheric moisture. Water vapor is one of the most important parts of the atmosphere.

Water in gaseous form. It is one of the most import constituents of the atmosphere. Due to its molecular content, air containing water vapor is lighter than dry air. This contributes to the reason why [..]

Water

Water in a gaseous state.

Water in gaseous form. It is one of the most import constituents of the atmosphere. Due to its molecular content, air containing water vapor is lighter than dry air. This contributes to the reason why moist air has a tendency to rise.

In air conditioning, the water in the atmosphere.

water in a gaseous state, especially when diffused in the atmosphere steam

(n) - the gaseous state of water

Water present in the atmosphere in gaseous form; the source of all forms of condensation and precipitation. Water vapor, clouds, and carbon dioxide are the main atmospheric components in the exchange of terrestrial radiation in the troposphere, serving as a regulator of planetary temperatures via the greenhouse effect. Approximately 50 percent of t [..]
