Beverages[ edit ] Tonic waterin normal light and ultraviolet " black light ". The quinine content of tonic water causes it to fluoresce under black light. Quinine is a flavour component of tonic water and bitter lemon drink mixers.
History of use Discovery and early application The first discoveries of natural gas seeps were made in Iran between and bce. Many early writers described the natural petroleum seeps in the Middle Eastespecially in the Baku region of what is now Azerbaijan. The use of natural gas was mentioned in China about bce.
It was in China in bce that the first known well was drilled for natural gas, to reported depths of metres feet. The Chinese drilled their wells with bamboo poles and primitive percussion bits for the express purpose of searching for gas in limestones dating to the Late Triassic Epoch about million to million years ago in an anticline west of modern Chongqing.
The gas was burned to dry the rock salt found interbedded in the limestone. Eventually wells were drilled to depths approaching 1, metres 3, feetand more than 1, wells had been drilled into the anticline by Natural gas was unknown in Europe until its discovery in England inand even then it did not come into wide use.
Instead, gas obtained from carbonized coal known as town gas became the primary fuel for illuminating streets and houses throughout much of Europe from on. In North America the first commercial application of a petroleum product was the utilization of natural gas from a shallow well in FredoniaNew York, in The gas was distributed through a small-bore lead pipe to consumers for lighting and cooking.
Improvements in gas pipelines Throughout the 19th century the use of natural gas remained localized because there was no way to transport large quantities of gas over long distances. Natural gas remained on the sidelines of industrial development, which was based primarily on coal and oil.
An important breakthrough in gas-transportation technology occurred in with the invention of leakproof pipeline coupling. Nonetheless, materials and construction techniques remained so cumbersome that gas could not be used more than km miles from a source of supply.
Thus, associated gas was mostly flared i. Long-distance gas transmission became practical during the late s because of further advances in pipeline technology.
From to more than 10 major transmission systems were constructed in the United States. Each of these systems was equipped with pipes having diameters of approximately 50 cm 20 inches and extended more than km miles.
Following World War IIa large number of even longer pipelines of increasing diameter were constructed.
The fabrication of pipes having a diameter of up to cm 60 inches became possible. Since the early s the longest gas pipelines have had their origin in Russia. The sea is more than metres 2, feet deep along some parts of that route.Natural rubber, also called India rubber or caoutchouc, as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds, plus water.
Malaysia and Indonesia are two of the leading rubber producers. Rubber Band Powered Vehicle Part A: Introduction a. Theoretical Background The rubber band car is a car powered by a single rubber band.
Energy efficiency is the amount of energy that is first stored in an object. The physic's definition of energy efficiency is very similar.
Thorium is a weakly radioactive metallic chemical element with symbol Th and atomic number Thorium is silvery and tarnishes black when it is exposed to air, forming thorium dioxide; it is moderately hard, malleable, and has a high melting schwenkreis.comm is an electropositive actinide whose chemistry is dominated by the +4 oxidation state; it is quite reactive and can ignite in air when.

Odorless, tasteless and natural resistance to bacteria buildup ; Reliable service at wide range of temperature; Let’s take a look at five of the best FDA-grade rubber materials: EPDM. EPDM Rubber is used in applications that demand both flexibility and ruggedness. Made from odorless and tasteless compounds, it can be wisely used in /5(9). Natural rubber does not age as well as many of the synthetics nor is it as chemically inert as some. It is inferior to many of the synthetics for heat aging, resistance to sunlight, oxygen, ozone, solvents or oils. Holds the heat longer than traditional rubber bottles Thermoplastic material that is odorless and recyclable Can be used hot or cold.
Hydrogen also has many other uses. In the chemical industry it is used to make ammonia for agricultural fertiliser (the Haber process) and cyclohexane and methanol, which are intermediates in the production of plastics and pharmaceuticals.
