A lower bound to temperature is absolute zero , defined as 0.00 K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to −273.15 °C on the Celsius scale , −459.67 °F on the Fahrenheit scale , and 0.00 °R on the Rankine scale . Since temperature relates to
340-406: Is the process of cooling an object by exposing it to air . This will only work if the air is at a lower temperature than the object, and the process can be enhanced by increasing the surface area , increasing the coolant flow rate, or decreasing the mass of the object. Another common method of cooling is exposing an object to ice , dry ice , or liquid nitrogen . This works by conduction ;

#1732776555106408-496: The thermal energy held by an object or a sample of matter, which is the kinetic energy of the random motion of the particle constituents of matter, an object will have less thermal energy when it is colder and more when it is hotter. If it were possible to cool a system to absolute zero, all motion of the particles in a sample of matter would cease and they would be at complete rest in the classical sense. The object could be described as having zero thermal energy. Microscopically in
442-421: The 17th century. The intellectual barrier was broken by Francis Bacon and Robert Boyle who followed him in this quest for knowledge of cold. Boyle did extensive experimentation during the 17th century in the discipline of cold, and his research on pressure and volume was the forerunner of research in the field of cold during the 19th century. He explained his approach as "Bacon's identification of heat and cold as
476-441: The 1920s expanded the refrigerator market during the 1930s. Home freezers as separate compartments (larger than necessary just for ice cubes) were introduced in 1940. Frozen foods, previously a luxury item, became commonplace. Cold has numerous physiological and pathological effects on the human body , as well as on other organisms. Cold environments may promote certain psychological traits, as well as having direct effects on
510-513: The 4th century AD, the brother of the Japanese emperor Nintoku gave him a gift of ice from a mountain. The Emperor was so happy with the gift that he named the first of June as the "Day of Ice" and ceremoniously gave blocks of ice to his officials. Even in ancient times, Shachtman says, in Egypt and India, night cooling by evaporation of water and heat radiation, and the ability of salts to lower

The central region is mainly occupied by the Fulani, Mambilla, Ndola, Tigon, Jibu, Wurbo, and Daka people. There are about 80 distinct ethnic groups and their languages in the state. The Taraba state was created out of the former Gongola state on 27 August 1991 by the military government of General Ibrahim Badamasi Babangida . The state
578-568: The State is that it encompasses part of the Mambilla Region which is famed as the Bantu cradle, having been occupied for some five millennia to date (Schwartz, 1972; Zeitlyn & Connell, 2003). The state government is led by a democratically elected governor who works closely with members of the state's House of Assembly. The capital city of the state is Jalingo. The governor of the state
612-451: The ability to move. Shivering is one of the first physiological responses to cold. Even at low temperatures, the cold can massively disrupt blood circulation. Extracellular water freezes and tissue is destroyed. It affects fingers, toes, nose, ears and cheeks particularly often. They discolor, swell, blister, and bleed. The so-called frostnip leads to local frostbite or even to the death of entire body parts. Only temporary cold reactions of
646-403: The cold of the latter, the nitre by adding to its own cold, but the salt by supplying activity to the cold snow." This explanation on the cold inducing aspects of nitre and salt was tried then by many scientists. Shachtman says it was the lack of scientific knowledge in physics and chemistry that had held back progress in the beneficial use of ice until a drastic change in religious opinions in
680-470: The description of quantum mechanics , however, matter still has zero-point energy even at absolute zero, because of the uncertainty principle . Cooling refers to the process of becoming cold, or lowering in temperature . This could be accomplished by removing heat from a system, or exposing the system to an environment with a lower temperature. Coolants are fluids used to cool objects, prevent freezing and prevent erosion in machines. Air cooling
714-425: The freezing temperature of water was practiced. The ancient people of Rome and Greece were aware that boiled water cooled quicker than the ordinary water; the reason for this is that with boiling of water carbon dioxide and other gases, which are deterrents to cooling, are removed; but this fact was not known till the 17th century. Shachtman says that King James VI and I supported the work of Cornelis Drebbel as

#1732776555106748-645: The heat is transferred from the relatively warm object to the relatively cold coolant. Laser cooling and magnetic evaporative cooling are techniques used to reach very low temperatures. In ancient times, ice was not adopted for food preservation but used to cool wine which the Romans had also done. According to Pliny , Emperor Nero invented the ice bucket to chill wines instead of adding it to wine to make it cold as it would dilute it. Some time around 1700 BC Zimri-Lim , king of Mari Kingdom in northwest Iraq had created an "icehouse" called bit shurpin at

"Three children's bodies have been found after a boat carrying passengers capsized on Saturday while traveling from the Mayo-Renewo market to the Karim Lamido neighborhood of Taraba," according to diverse media reports. On Sunday, October 29, 2023, Abdullahi Usman,
816-410: The mid-19th century to the 1930s, when the refrigerator was introduced into the home. Most municipally consumed ice was harvested in winter from snow-packed areas or frozen lakes, stored in ice houses , and delivered domestically as iceboxes became more common. In 1913, refrigerators for home use were invented. In 1923 Frigidaire introduced the first self-contained unit. The introduction of Freon in

Crops such as maize , rice , sorghum , millet , cassava , and yam are also produced in commercial quantity. In addition, cattle , sheep and goats are reared in large numbers, especially on the Mambilla Plateau, and along the Benue and Taraba valleys . Similarly,
884-620: The people of Taraba state undertake other livestock production activities like poultry production, rabbit breeding and pig farming in fairly large scale. In February 2024, the World Bank in Nigeria announced plans to empower 5,200 female livestock farmers in the state. Communities living on the banks of River Benue , River Taraba, River Donga and Ibi, engage in fishing all year round. Other occupational activities such as pottery, cloth-weaving, dyeing, mat-making, carving, embroidery and blacksmithing are also carried out in various parts of
918-477: The right and left hands of nature". Boyle also refuted some of the theories mooted by Aristotle on cold by experimenting on transmission of cold from one material to the other. He proved that water was not the only source of cold but gold, silver and crystal, which had no water content, could also change to severe cold condition. In the United States from about 1850 till end of 19th century export of ice
952-493: The skin are without consequences. As blood vessels contract, they become cool and pale, with less oxygen getting into the tissue. Warmth stimulates blood circulation again and is painful but harmless. Comprehensive protection against the cold is particularly important for children and for sports. Extreme cold temperatures may lead to frostbite , sepsis , and hypothermia , which in turn may result in death. A common, but false, statement states that cold weather itself can induce
986-491: The state's police spokesperson, confirmed the incident to TheCable . Given that they are passengers from the Mayo-Renewo market traveling to Karim Lamido, he said the exact number of passengers on that boat has yet to be determined. The climate of Taraba state is marked by an annual average temperature of 33 ° C but high level of cold in January and an increased rainfall in August. The percentage of rainfall in Taraba state

Taraba state has abundant natural resources for industrial and commercial use, these include: The government has made concerted efforts to improve areas of tourist attractions like Mambilla Tourist Center, Gumpti Park and game reserve in Gashaka . Karimjo Abedahh festival and the Nwunyu fishing festival in Ibi , all this is usually held in April of each year where activities such as canoe racing, swimming competition and cultural dances are held. Other festivals are Purma of
1054-461: Was an incredible spectacle, says Shachtman. Several years before, Giambattista della Porta had demonstrated at the Abbey "ice fantasy gardens, intricate ice sculptures" and also iced drinks for banquets in Florence . The only reference to the artificial freezing created by Drebbel was by Francis Bacon . His demonstration was not taken seriously as it was considered one of his magic tricks, as there

1088-450: Was filled with ice. In 1825, ice harvesting by use of a horse drawn ice cutting device was invented by Nathaniel J. Wyeth. The cut blocks of uniform size ice was a cheap method of food preservation widely practiced in the United States. Also developed in 1855 was a steam powered device to haul 600 tons of ice per hour. More innovations ensued. Devices using compressed air as a refrigerants were invented. Iceboxes were in widespread use from
1122-507: Was no practical application then. Drebbel had not revealed his secrets. Shachtman says that Lord Chancellor Bacon, an advocate of experimental science, had tried in Novum Organum , published in the late 1620s, to explain the artificial freezing experiment at Westminster Abbey, though he was not present during the demonstration, as " Nitre (or rather its spirit) is very cold, and hence nitre or salt when added to snow or ice intensifies
