Hence, temperature determines the concentration of vapor of the flammable liquid in the air.

Hearing underwater Hearing threshold and the ability to localize sound sources are reduced underwater, in which the speed of sound is faster than in air.

Compressed air is air kept under a pressure that is greater than atmospheric pressure.

For example, the IR of air is approximately 1.0003 and the IR of water is approximately 1.333.

By the 13th century windmills had come into use to pump water out of areas below sea level.

When air rises, moist air cools at a lower rate than dry air.

Spread of the disease through the air between primates, including humans, has not been documented in either laboratory or natural conditions.

An air purifier is a device which removes contaminants from the air.

Air

Superior mirage A superior mirage occurs when the air below the line of sight is colder than the air above it.

Air detection

Air action

Air Cooler

This one we actually first discovered back in the air days the bad old air days, as we used to say when we were doing these kind of dives with air.

Moist air has more water vapor than dry air, so more latent heat is released into the parcel of moist air as it rises.

Houses in the Air

Air pollution

Instead of blowing a hurricane of chilled air through the stadium, we can use radiant cooling technologies, like a floor heating system where water pipes are embedded in the floor.

There's a convergence. So, wherever the rain is falling, the air is drawn towards it to replace the air that's rising.

Dry air does not have as much water vapor, therefore dry air cools at a higher rate with vertical movement than moist air.

It's acoustic vibrations in the air, little waves of energy in the air that tickle our eardrum.

This makes moist air generally less stable than dry air (see convective available potential energy).

The unit heats air at the bottom, reducing its relative humidity, and the natural tendency of hot air to rise brings this low humidity air into contact with the clothes.

He fights windmills.

The air conditioner was on.

The ratio of this air to the amount of air flowing through the engine core is the bypass ratio.

We spend an extraordinary amount of time in buildings that are extremely controlled environments, like this building here environments that have mechanical ventilation systems that include filtering, heating and air conditioning.

This lets them stay underwater longer for the same decompression requirement as for air, because less nitrogen is absorbed into the body's tissues.

A dual hose unit draws air to cool its condenser from outside instead of from inside the room, and thus is more effective than most single hose units.

This is possible because the lift force is generated at right angles to the air flow, which in gliding flight comes from slightly below the horizontal (because the bird is descending).

formula_4Where formula_5 is dynamic pressure.

Transport support base for the air staff.

Air pollution atmosphere

This in turn drew cooler air in from the lower vent, providing constant circulation of cooler air.

That is, for the same vertical movement, a parcel of moist air will be warmer than a parcel of dry air.

The weather front forms when the moist air over the Pacific meets the cooler continental air mass.

Many kinds of animals have vanished from the earth.

All hope of winning the game vanished.

Tear gas spreads through the air.

I was very scared.

That's because the bubble vanished into thin air.

If there is a warm layer of air higher up, an inversion can prevent thermals from rising high and the air is said to be stable.

The tendency of air and fire, on the other hand, was to move upwards, away from the center, with fire being lighter than air.

At some point, the force exerted by moving air upon the silk threads is great enough to launch the spider into the air.

As soon as it touches the water, you should hear a sort of sound of running air.
