Pork belly cut, showing layers of muscle and fat A pig being slow-roasted on a rotisserie. Pork is the culinary name for the meat of the pig (Sus domesticus).It is the most commonly consumed meat worldwide, [1] with evidence of pig husbandry dating back to 5000 BCE.
Pigs are extensively farmed, and therefore the terminology is well developed: Pig, hog, or swine, the species as a whole, or any member of it. The singular of "swine" is the same as the plural. Shoat (or shote), piglet, or (where the species is called "hog") pig, unweaned young pig, or any immature pig [23] Sucker, a pig between birth and weaning
A family of feral pigs. Pigs have escaped from farms and gone feral in many parts of the world. Feral pigs in the southeastern United States have migrated north to the Midwest, where many state agencies have programs to remove them. [35] [36] [37] Feral pigs in New Zealand and northern Queensland have caused substantial environmental damage.
Suidae is a family of artiodactyl mammals which are commonly called pigs, hogs, or swine. In addition to numerous fossil species, 18 extant species are currently recognized (or 19 counting domestic pigs and wild boars separately), classified into between four and eight genera .
Long isolated from other pigs on the many islands of Indonesia, Malaysia, and the Philippines, pigs have evolved into many different species, including wild boar, bearded pigs, and warty pigs. Humans have introduced pigs into Australia, North and South America, and numerous islands, either accidentally as escaped domestic pigs which have gone ...
The ground state of a quantum-mechanical system is its stationary state of lowest energy; the energy of the ground state is known as the zero-point energy of the system. An excited state is any state with energy greater than the ground state. In quantum field theory, the ground state is usually called the vacuum state or the vacuum. If more ...
The dissociation energy for the ground state molecule is 81.5 kcal/mol. [8] The electron affinity is roughly 0.3 eV, and the HB − ion is formed. [9] The dipole moment of the molecule in its ground state is 1.27 debye and for the first excited electronic state A 1 Π is 0.58 debye. [10]
The state with the lowest energy level, or ground state, is a singlet state (1 Σ + g ), which is systematically named ethene-1,2-diylidene or dicarbon(0•). There are several excited singlet and triplet states that are relatively close in energy to the ground state, which form significant proportions of a sample of dicarbon under ambient ...
