From Wiktionary under the GNU Free Documentation License. The atmosphere of Earth is a layer of gases surrounding the planet Earth that is retained by Earth's gravity. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night. Dry air contains roughly (by volume) 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1%. The atmosphere has a mass of about 5 × 10 kg, three quarters of which is within about 11 km (6.8 mi; 36,000 ft) of the surface. The atmosphere becomes thinner and thinner with increasing altitude, with no definite boundary between the atmosphere and outer space. An altitude of 120 km (75 mi) is where atmospheric effects become noticeable during atmospheric reentry of spacecraft. The Kármán line, at 100 km (62 mi), also is often regarded as the boundary between atmosphere and outer space. From Wikipedia under the

As others have said, an air conditioner is the machine, air conditioning is the result. Note that the machine is an object, therefore countable--you need "an". "Air conditioning" is intangible, therefore non-countable--no "an". >>I knew that we can say that "this car comes with an air conditioning" . You would say just "comes with air conditioning" or "an air conditioning system". >>Does your apartment has an air conditioning /conditioner?

Q. When I turn on my central air, I am only getting cold air weakly through the vents for about any hour. After that, you cannot feel the air even though the air conditioning unit is still running. What causes this? I ran it last night and looked at the coils once the air stopped coming through the vents and they had frost on them. I couldn't tell if there was something blocking the air flow, so does this mean I am low on freon? Asked by Building - Tue Jun 15 09:09:44 2010 - - 4 Answers - 0 Comments A. It sounds like the coil is freezing up, caused by extremely dirty coils, a freon leak, or some sort of air flow restriction..
