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

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

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

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

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

At 20 C and 101.325 kPa, dry air has a density of 1.2041 kg m3.

I love the way the air is so fresh and clean after it rains.

Using a humidifier, especially in the winter, can help by adding moisture to the dry indoor air.

The air is generally very dry consequently, the daily and annual range of temperature is quite large.

More tantalizing for humanity s need for widely available, clean base load power is the non conventional geothermal energy called hot dry rocks, or HDR.

Barmini says the device, called the APFI Barelec, will clean 80 of the air impurities coming from factory chimneys.

Clean air is a basic requirement for human health and welfare and an important prerequisite for sustainable economic development.

So when water molecules (water vapor) are added to a given volume of air, the dry air molecules must decrease by the same number, to keep the pressure or temperature from increasing.

And the priests that bare the ark of the covenant of the LORD stood firm on dry ground in the midst of Jordan, and all the Israelites passed over on dry ground, until all the people were passed clean over Jordan.

Sulfate aerosols have declined significantly since 1970 with the Clean Air Act in the United States and similar policies in Europe.

Instead of using hot air to dry the clothing, mechanical steam compression dryers use water recovered from the clothing in the form of steam.

Syria claims that, as a result of exposure to these air masses, wet and dry depositions of pollutants occurred over its south eastern territories.

In respect to pollution with black smoke (soot), the city zone can be divided into two zones (a) the zone of clean air, and (b) a zone of low to medium polluted air during the year, and in winter season, extremely polluted air.

This, in turn, reflects global economic and population growth, with resulting shortages of critical resources fuel, food, and clean air and water.

But this is just a start we have treated our most precious resources clean water and air as if they were free.

Global, because the array of services that natural ecosystems provide, such as clean air and fresh water, benefit people far beyond national borders.

This movement managed to force the first environmental laws out of the conservative Nixon administration the National Environmental Act of 1969, the Clean Air Act of 1970, the Clean Water Act of 1972, and the Endangered Species Act of 1973.

Therefore, air quality is an urgent and immediate issue for the nation that is already suffering from an extremely hot and dry climate, severe drought and recurrent famine.

In 1975, the US state of Minnesota enacted the Minnesota Clean Indoor Air Act , making it the first state to restrict smoking in most public spaces.

Because they're doing so much dirty production in Asia now, because the environmental laws don't protect the people in Asia now, almost all of the clean air gains and the toxic air gains that we've achieved here in California have been wiped out by dirty air coming over from Asia.
