Ice is water frozen into a solid state. Depending on the presence of impurities such as particles of soil or bubbles of air, it can appear transparent or a more or less opaque bluish-white color.
In the Solar System, ice is abundant and occurs naturally from as close to the Sun as Mercury to as far as away the Oort cloud objects. Beyond the Solar System, it occurs as interstellar ice. It is abundant on Earth's surface - particularly in the polar regions and above the snow line - and, as a common form of precipitation and deposition, plays a key role in Earth's water cycle and climate. It falls as snowflakes and hail or occurs as frost, icicles or ice spikes.
Ice molecules can exhibit up to sixteen different phases (packing geometries) that depend on temperature and pressure. When water is cooled rapidly (quenching), up to three different types of amorphous ice can form depending on the history of its pressure and temperature. When cooled slowly correlated proton tunneling occurs below 20 K giving rise to macroscopic quantum phenomena. Virtually all the ice on Earth's surface and in its atmosphere is of a hexagonal crystalline structure denoted as ice Ih (spoken as "ice one h") with minute traces of cubic ice denoted as ice Ic. The most common phase transition to ice Ih occurs when liquid water is cooled below 0°C (273.15K, 32°F) at standard atmospheric pressure. It may also be deposited directly by water vapor, as happens in the formation of frost. The transition from ice to water is melting and from ice directly to water vapor is sublimation.
Root beer is a sweet soda traditionally made using the Sassafras tree Sassafras albidum (sassafras) or the vine Smilax ornata (sarsaparilla) as the primary flavor. Root beer may be alcoholic or non-alcoholic, come naturally decaffeinated or have caffeine added, and may be carbonated or non-carbonated. Root beer usually has a thick foamy head when poured. Modern, commercially produced root beer is generally sweet, foamy, carbonated, non-alcoholic, and is flavoured using artificial sassafras flavouring. Sassafras root is still used to flavor traditional root beer, although since sassafras was banned by the FDA because of the carcinogenicity of its constituent safrole, most commercial recipes do not contain sassafras. Some commercial root beers do use a safrole-free sassafras extract.
Cream is a dairy product composed of the higher-butterfat layer skimmed from the top of milk before homogenization. In un-homogenized milk, the fat, which is less dense, will eventually rise to the top. In the industrial production of cream, this process is accelerated by using centrifuges called "separators". In many countries, cream is sold in several grades depending on the total butterfat content. Cream can be dried to a powder for shipment to distant markets. Cream has high levels of saturated fat. Cream skimmed from milk may be called "sweet cream" to distinguish it from whey cream skimmed from whey, a by-product of cheese-making. Whey cream has a lower fat content and tastes more salty, tangy and "cheesy". In many countries, cream is usually sold partially fermented: sour cream, cr?me fraîche, and so on.
Coca-Cola (often referred to simply as Coke) is a carbonated soft drink produced by The Coca-Cola Company of Atlanta, Georgia. Originally intended as a patent medicine, it was invented in the late 19th century by John Pemberton.
Coca-Cola was bought out by businessman Asa Griggs Candler, whose marketing tactics led Coke to its dominance of the world soft-drink market throughout the 20th century. The name refers to two of its original ingredients: kola nuts, a source of caffeine, and coca leaves. The current formula of Coca-Cola remains a trade secret, although a variety of reported recipes and experimental recreations have been published.
