Water
Water (chemical formula: H2O) is a transparent fluid which forms the world's streams, lakes, oceans and rain, and is the major constituent of the fluids of organisms. As a chemical compound, a water molecule contains one oxygen and two hydrogen atoms that are connected by covalent bonds. Water is a liquid at standard ambient temperature and pressure, but it often co-exists on Earth with its solid state, ice; and gaseous state, steam (water vapor). It also exists as snow, fog, dew and cloud.
Water covers 71% of the Earth's surface. It is vital for all known forms of life. On Earth, 96.5% of the planet's crust water is found in seas and oceans, 1.7% in groundwater, 1.7% in glaciers and the ice caps of Antarctica and Greenland, a small fraction in other large water bodies, and 0.001% in the air as vapor, clouds (formed of ice and liquid water suspended in air), and precipitation. Only 2.5% of this water is freshwater, and 98.8% of that water is in ice (excepting ice in clouds) and groundwater. Less than 0.3% of all freshwater is in rivers, lakes, and the atmosphere, and an even smaller amount of the Earth's freshwater (0.003%) is contained within biological bodies and manufactured products. A greater quantity of water is found in the earth's interior.
Water (Elitsa & Stoyan song)
"Water" (Bulgarian script: Вода) was the Bulgarian entry in the Eurovision Song Contest 2007, performed in Bulgarian by Elitsa Todorova & Stoyan Yankoulov. This was the first occasion on which the Bulgarian language was used on the Eurovision stage, previous Bulgarian entries being performed in English. Originally titled "Voda", the song had its title translated to English for the Contest.
The song is an up-tempo number with techno influences, as well as a jaw harp and traditional percussion. Todorova sings folk-inspired lyrics dealing with a young girl meeting a young boy riding a horse.
The performance in the semi-final featured the duo wearing what looked like armour, while they were wearing more mainstream clothes in the final. The performances were also notable for the high-energy percussion performances of both musicians.
As Bulgaria had not finished the previous Contest in the top ten, the song was performed in the semi-final. Here, it was performed first (preceding Israel's Teapacks with "Push The Button"). At the close of voting, it had received 146 points, placing 6th in a field of 28 and qualifying Bulgaria for its first final.
Water (Conor Oberst album)
Water is the debut album of Conor Oberst and the first release on Lumberjack Records, the label that would become Saddle Creek. He was only 13 years old at the time. It was released as a cassette tape, and came in 300 copies only, in five different colors on the covers (yellow, blue, green, brown and white).

Tanker (ship)
A 'tanker (or tank ship or tankship) is a merchant vessel designed to transport liquids or gases in bulk. Major types of tankship include the oil tanker, the chemical tanker, and gas carrier. In the United States Navy and Military Sealift Command, any type of tanker used to refuel other ships is called an oiler
Background
Tankers can range in size of capacity from several hundred tons, which includes vessels for servicing small harbours and coastal settlements, to several hundred thousand tons, for long-range haulage. Besides ocean- or seagoing tankers there are also specialized inland-waterway tankers which operate on rivers and canals with an average cargo capacity up to some thousand tons. A wide range of products are carried by tankers, including:
Tankers are a relatively new concept, dating from the later years of the 19th century. Before this, technology had simply not supported the idea of carrying bulk liquids. The market was also not geared towards transporting or selling cargo in bulk, therefore most ships carried a wide range of different products in different holds and traded outside fixed routes. Liquids were usually loaded in casks—hence the term "tonnage", which refers to the volume of the holds in terms of how many tuns or casks of wine could be carried. Even potable water, vital for the survival of the crew, was stowed in casks. Carrying bulk liquids in earlier ships posed several problems:
DC-10 Air Tanker
The DC-10 Air Tanker is a series of American wide-body jet air tankers, which have been in service as an aerial firefighting unit since 2006. The aircraft, operated by the joint technical venture 10 Tanker Air Carrier, are converted McDonnell Douglas DC-10s, and are primarily used to fight wildfires, typically in rural areas. The turbofan-powered aircraft carry up to 12,000 US gallons (45,000 liters) of water or fire retardant in an exterior belly-mounted tank, the contents of which can be released in eight seconds. Three air tankers are currently in operation, with the call-signs Tanker 910, Tanker 911 and Tanker 912.
Development
10 Tanker began researching the development of Next Generation airtankers in 2002. Company personnel were assembled with an extensive history of heavy jet operations, modifications and ownership. After two years of research into aerial firefighting requirements and future direction, 10 Tanker selected the DC10 type for development. A Supplemental Type Certificate (STC) from the FAA for modifications of DC10 aircraft to be used for the aerial dispersant of liquids was issued in March 2006. 10 Tanker then obtained a 14 CFR Part 137 Operating Certificate for aerial firefighting and IAB approval for agency use. The first converted aircraft, registered as N450AX, was originally delivered as a civil passenger plane to National Airlines in 1975, and subsequently flew for Pan Am, American Airlines, Hawaiian Airlines and Omni Air International.
