Celsius, Fahrenheit temperature, and the relationship between absolute temperature

Temperature is the degree of cold and hot object. Such as cooking temperature, fermentation temperature, mash into the tower at the top of the column temperature, temperature and moderate tower kettle temperature, etc. To the discretion of the measured temperature values, depending on the principle of production of a variety of types of thermometer. Ordinary thermometer is made according to the heat bilges cold shrink phenomenon of liquid, the commonly used, which has two kinds of mercury thermometer and alcohol thermometer. And instructions of the bimetallic thermometer used in industrial site, is made according to the principle of heat bilges cold shrink of metal. Domestic general Celsius scale at present, it is distilled water ice - under atmospheric pressure - The temperature of the water mixture as 0 degrees, the boiling point of 100 degrees. In between 0 and 100 degrees is divided into 100 equal pieces, called the each equal 1 degree. The unit of it do ℃. In addition to the Fahrenheit scale, its unit do remember & deg; F it is ice - - Salt mixture temperature is 32 & deg; F, with the pure water under the conditions of the atmospheric temperature is 212 & deg; F, to a healthy person's blood temperature for 95 & deg; F。 This is Britain, the United States and other countries commonly used scale. In distillation calculations, often USES the absolute scale, also called the international temperature scale or kelvin scale, namely the Celsius temperature value plus 273. The values obtained after 15 its units do remember & deg; The above three kinds of scale, the relationship between the conversion to each other by the following formula: Celsius temperature ℃ = 5/9 & times; ( Fahrenheit temperature & deg; F－32) Fahrenheit ℉ = 9/5 & times; ( Celsius temperature 32 ℃ +) Absolute temperature & deg; K = Duo Fahrenheit 10 273 ℃. 15, for example, ask each 25 ℃ rather Fahrenheit and Celsius absolute temperature how many degrees? Can be calculated as follows: Fahrenheit 9/5 = & times; 250 = 77 (32 ℉) Absolute temperature = 250, 273. 15 = 298. 15 ( ° K) From the above calculation is 25 ℃ is equivalent to Fahrenheit 77 & deg Celsius; 298 F, is equal to the absolute temperature. 15° K。 Obviously, the temperature change 1 degrees Celsius, is equal to the absolute temperature change 1 degree.
