Gas

Gas is one of the four fundamental states of matter (the others being solid, liquid, and plasma). A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide). A gas mixture would contain a variety of pure gases much like the air. What distinguishes a gas from liquids and solids is the vast separation of the individual gas particles. This separation usually makes a colorless gas invisible to the human observer. The interaction of gas particles in the presence of electric and gravitational fields are considered negligible as indicated by the constant velocity vectors in the image. One type of commonly known gas is steam.

The gaseous state of matter is found between the liquid and plasma states, the latter of which provides the upper temperature boundary for gases. Bounding the lower end of the temperature scale lie degenerative quantum gases which are gaining increasing attention. High-density atomic gases super cooled to incredibly low temperatures are classified by their statistical behavior as either a Bose gas or a Fermi gas. For a comprehensive listing of these exotic states of matter see list of states of matter.

New Zealand

New Zealand (/njuːˈziːlənd/ new-ZEE-lənd, Māori: Aotearoa [aɔˈtɛaɾɔa]) is an island country in the southwestern Pacific Ocean. The country geographically comprises two main landmasses – that of the North Island, or Te Ika-a-Māui, and the South Island, or Te Waipounamu – and numerous smaller islands. New Zealand is situated some 1,500 kilometres (900 mi) east of Australia across the Tasman Sea and roughly 1,000 kilometres (600 mi) south of the Pacific island areas of New Caledonia, Fiji, and Tonga. Because of its remoteness, it was one of the last lands to be settled by humans. During its long isolation, New Zealand developed a distinctive biodiversity of animal, fungal and plant life. The country's varied topography and its sharp mountain peaks, such as the Southern Alps, owe much to the tectonic uplift of land and volcanic eruptions. New Zealand's capital city is Wellington, while its most populous city is Auckland.

Somewhere between 1250 and 1300 CE, Polynesians settled in the islands that were to become New Zealand, and developed a distinctive Māori culture. In 1642, Abel Tasman, a Dutch explorer, became the first European to sight New Zealand. In 1840, representatives of the British Crown and Māori Chiefs signed the Treaty of Waitangi, making New Zealand a British colony. Today, the majority of New Zealand's population of 4.5 million is of European descent; the indigenous Māori are the largest minority, followed by Asians and Pacific Islanders. Reflecting this, New Zealand's culture is mainly derived from Māori and early British settlers, with recent broadening arising from increased immigration. The official languages are English, Māori and New Zealand Sign Language, with English predominant.

British Gas

British Gas is an energy and home services provider in the United Kingdom. It is the trading name of British Gas Services Limited and British Gas New Heating Limited, both subsidiaries of Centrica. Serving around twelve million homes in the UK, British Gas is the biggest UK energy supplier and is considered one of the Big Six dominating the gas and electricity market in the United Kingdom.

The brand British Gas remains from the demerger of the British Gas Corporation in 1997, which formed Centrica, BG Group and Transco. The British Gas Corporation was a result of the restructuring of the UK gas industry following the Gas Act 1972. The act merged all of the area boards and created the British Gas Corporation.

The British Gas Corporation was privatised as British Gas plc by the Thatcher government and on 8 December 1986 its shares were floated on the London stock market.

Centrica trades as Scottish Gas in Scotland.

History

1812-1948

The Gas Light and Coke Company was the first public utility company in the world. It was founded by Frederick Albert Winsor and incorporated by Royal Charter on 30 April 1812 under the seal of King George III. It continued to thrive for the next 136 years, expanding into domestic services whilst absorbing many smaller companies including the Aldgate Gas Light and Coke Company (1819), the City of London Gas Light and Coke Company (1870), the Equitable Gas Light Company (1871), the Great Central Gas Consumer's Company (1870), Victoria Docks Gas Company (1871), Western Gas Light Company (1873), Imperial Gas Light and Coke Company (1876), Independent Gas Light and Coke Company (1876), the London Gas Light Company (1883), Richmond Gas Company (1925), Brentford Gas Company (1926), Pinner Gas Company (1930) and Southend-on-Sea and District Gas Company (1932).
