PotassiumPotassium is the chemical element with the symbol K (from Neo-Latin kalium) and atomic number 19. It is a silvery white metal that is soft enough to easily cut with a knife. Potassium metal reacts rapidly with atmospheric oxygen to form flaky white potassium peroxide in only seconds of exposure. It was first isolated from potash, the ashes of plants, from which its name derives. In the periodic table, potassium is one of the alkali metals, all of which have a single valence electron in the outer electron shell, which is easily removed to create an ion with a positive charge (which combines with anions to form salts).
PigThe pig (Sus domesticus), often called swine (: swine), hog, or domestic pig when distinguishing from other members of the genus Sus, is an omnivorous, domesticated, even-toed, hoofed mammal. It is variously considered a subspecies of Sus scrofa (the wild boar or Eurasian boar) or a distinct species. The pig's head-plus-body length ranges from , and adult pigs typically weigh between , with well-fed individuals even exceeding this range. The size and weight of hogs largely depends on their breed.
Punk subcultureThe Punk subculture is an identifiable subgroup within a society, characterized by similar ideologies, values, interests, and forms of expression reflected in music, fashion, arts, dance, literature, film, and politics. The Punk movement emerged in the mid-1970s as a response to societal norms, in a profound statement of defiance, individuality, and a yearning for authenticity in an ever-conforming world. Initially, the term 'punk' was used in a derogatory way - a criminal or troublemaker - and was later repurposed to convey a 'counter' subculture that revealed its outsider status.
SheepskinSheepskin is the hide of a sheep, sometimes also called lambskin. Unlike common leather, sheepskin is tanned with the fleece intact, as in a pelt. Sheepskin is used to produce sheepskin leather products and soft wool-lined clothing or coverings, including gloves, hats, slippers, footstools, automotive seat covers, baby and knee rugs and pelts. Sheepskin numnahs, saddle pads, saddle seat covers, sheepskin horse boots, tack linings and girth tubes are also made and used in equestrianism.
ThailandThailand (Thai: ประเทศไทย) (ˈtaɪlænd,_-lənd, ), officially the Kingdom of Thailand and historically known as Siam (saɪ'æm,_ˈsaɪæm, ), is a country in Southeast Asia on the Indochinese Peninsula. With a population of almost 70 million, it spans . Thailand is bordered to the north by Myanmar and Laos, to the east by Laos and Cambodia, to the south by the Gulf of Thailand and Malaysia, and to the west by the Andaman Sea; it also shares maritime borders with Vietnam to the southeast, and Indonesia and India to the southwest.
MexicoMexico (Spanish: México), officially the United Mexican States, is a country in the southern portion of North America. It is bordered to the north by the United States; to the south and west by the Pacific Ocean; to the southeast by Guatemala, Belize, and the Caribbean Sea; and to the east by the Gulf of Mexico. Mexico covers 1,972,550 km2 (761,610 sq mi), making it the world's 13th-largest country by area; with a population of over 126 million, it is the 10th-most-populous country and has the most Spanish speakers.
BiodegradationBiodegradation is the breakdown of organic matter by microorganisms, such as bacteria and fungi. It is generally assumed to be a natural process, which differentiates it from composting. Composting is a human-driven process in which biodegradation occurs under a specific set of circumstances. The process of biodegradation is threefold: first an object undergoes biodeterioration, which is the mechanical weakening of its structure; then follows biofragmentation, which is the breakdown of materials by microorganisms; and finally assimilation, which is the incorporation of the old material into new cells.
WaxWaxes are a diverse class of organic compounds that are lipophilic, malleable solids near ambient temperatures. They include higher alkanes and lipids, typically with melting points above about 40 °C (104 °F), melting to give low viscosity liquids. Waxes are insoluble in water but soluble in nonpolar organic solvents such as hexane, benzene and chloroform. Natural waxes of different types are produced by plants and animals and occur in petroleum.
HexaneHexane (ˈhɛkseɪn) is an organic compound, a straight-chain alkane with six carbon atoms and has the molecular formula C6H14. It is a colorless liquid, odorless when pure, and with boiling points approximately . It is widely used as a cheap, relatively safe, largely unreactive, and easily evaporated non-polar solvent, and modern gasoline blends contain about 3% hexane. The term hexanes refers to a mixture, composed largely (>60%) of hexane, with varying amounts of the isomeric compounds 2-methylpentane and 3-methylpentane, and, possibly, smaller amounts of nonisomeric C5, C6, and C7 (cyclo)alkanes.
ScabbardA scabbard is a sheath for holding a sword, dagger, knife, or similar edged weapon. As well, rifles may be stored in a scabbard by horse riders. Military cavalry and cowboys had scabbards for their saddle ring lever-action carbines and rifles on their horses for transportation and protection. Scabbards have been made of many materials over the millennia, including leather, wood, and metal such as brass or steel. Most commonly, sword scabbards were worn suspended from a sword belt or shoulder belt called a baldric.
