Map Of Earth Made Out Of Matches

A match is a tool that is used to start a fire. Usually, modern matches are made of tiny wooden sticks or stiff paper. One end is coated with a material that can be ignited by frictional heat generated by striking the match against a suitable surface.  Wooden matches are packaged in matchboxes, and paper matches are partially cut into rows and stapled into matchbooks.

The coated end of a match, known as the match “head”, contains either phosphorus or phosphorus sesquisulfide as the active ingredient and gelatin as a binder. There are two different types of matches: safety matches, which can be struck only against a specially prepared surface, and strike-anywhere matches, for which any suitably frictional surface can be used. Some match-like compositions, known as electric matches, are ignited electrically and do not make use of heat from friction.

Historically, the term match referred to lengths of cord (later cambric) impregnated with chemicals, and allowed to burn continuously. These were used to light fires and fire guns and cannons. Such matches were characterized by their burning speed i.e. quick match and slow match. Depending on its formulation, a slow match burns at a rate of around 30 cm per hour and a quick match at 4 to 60 cm per minute.

The modern equivalent of this sort of match is the simple fuse, still used in pyrotechnics to obtain a controlled time delay before ignition. The original meaning of the word still persists in some pyrotechnics terms, such as black match (a black-powder-impregnated fuse) and Bengal match (a firework akin to sparklers producing a relatively long-burning, colored flame).

Scary Secret In An Old Fireplace

A fireplace is an architectural structure that is made to contain a fire. Fireplaces are used at the present time mostly for the relaxing ambiance they create. Historically they were used for the practical purposes of heating, cooking, and heating water for laundry and domestic uses.

A fire is contained in a firebox or fire pit; a chimney or other flues are built to allow exhaust to escape. A fireplace may have: a foundation; a hearth; a firebox; a mantelpiece; a chimney crane, used in kitchen and laundry fireplaces; a grate; a lintel; a lintel bar; over mantel; a damper; a smoke chamber; a throat; a flue.

On the exterior there is often a corbeled brick crown; the projecting courses of brick act as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud serves to keep rainwater out of the exterior of the chimney; rain in the chimney is a much greater problem in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, which soaks up all but the most violent rain. Some chimneys have a spark arrestor incorporated into the crown or cap.

Fireplaces have variable heat efficiency. Organizations like the Environmental Protection Agency and the Washington Department of Ecology warn that, according to various studies, fireplaces can pose a significant health risk.

Very Dangerous Burning Drink

A drink, or beverage, is a kind of liquid which is specifically prepared for human consumption. There are many groups ford rinks. It can be divided into various groups such as plain water, alcohol, non alcoholic drinks, soft drinks (carbonated drinks), fruit or vegetable juices and hot drinks. In addition to fulfilling a basic need, drinks form part of the culture of human society.

An alcoholic beverage is a drink that contains ethanol, commonly known as alcohol (although in chemistry the definition of “alcohol” includes many other compounds).Beer has been a part of human culture for 8,000 years. In many countries, drinking alcoholic beverages in a local bar or pub is a cultural tradition. Asian countries produce several varieties of alcoholic beverages (e.g. rice wine, Tongba a millet brew). The term “soft drink” specifies the absence of alcohol in contrast to “hard drink” and “drink”.

The term “drink” is neutral but often denotes alcoholic content. Beverages such as soda pop, sparkling water, iced tea, lemonade, root beer, and fruit punch are the most common soft drinks. Milk, hot chocolate, tea, coffee, milkshakes, and tap water are not considered to be soft drinks. Some carbonated soft drinks are available in versions that are sweetened with a sugar substitute. Some substances may be defined as either food or drink, and accordingly may be eaten with a spoon or drunk, depending upon their thickness and solutes.

One Of The Biggest Fires Ever

Fire is the rapid oxidation of a material in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. Slower oxidative processes like rusting or digestion are not included by this definition.

The flame is the visible portion of the fire. If hot enough, the gases may become ionized to produce plasma. Depending on the substances alight, and any impurities outside, the color of the flame and the fire’s intensity will be different.

Fire in its most common form can result in conflagration, which has the potential to cause physical damage through burning. Fire is an important process that affects ecological systems across the globe. The positive effects of fire include stimulating growth and maintaining various ecological systems. Fire has been used by humans for cooking, generating heat, signaling, and propulsion purposes. The negative effects of fire include water contamination, soil erosion, atmospheric pollution and hazard to human and animal life.

Fires start when a flammable and/or a combustible material, in combination with a sufficient quantity of an oxidizer such as oxygen gas or another oxygen-rich compound (though non-oxygen oxidizers exist that can replace oxygen), is exposed to a source of heat or ambient temperature above the flash point for the fuel/oxidizer mix, and is able to sustain a rate of rapid oxidation that produces a chain reaction. This is commonly called the fire tetrahedron. Fire cannot exist without all of these elements in place and in the right proportions.

Extremely Dangerous Football From Indonesia

Football refers to a number of sports that involve, to varying degrees, kicking a ball with the foot to score a goal. The most popular of these sports worldwide is association football, more commonly known as just “football” or “soccer”.

Unqualified, the word football applies to whichever form of football is the most popular in the regional context in which the word appears, including association football, as well as American football, Australian rules football, Canadian football, Gaelic football, rugby league, rugby union and other related games. These variations of football are known as football codes.

Various forms of football can be identified in history, often as popular peasant games. Contemporary codes of football can be traced back to the codification of these games at English public schools in the eighteenth and nineteenth century. The influence and power of the British Empire allowed these rules of football to spread, including to areas of British influence outside of the directly controlled Empire, though by the end of the nineteenth century, distinct regional codes were already developing: Gaelic Football, for example, deliberately incorporated the rules of local traditional football games in order to maintain their heritage.

In 1888, The Football League was founded in England, becoming the first of many professional football competitions. In the twentieth century, the various codes of football have become amongst the most popular team sports in the world.
