英英 网络释义 kelvin n. 1. 开(开尔文温标的计量单位,1 开相当于 1 摄氏度,但以绝对零度为计算起点,水的冰点为 273.15 开)a unit for measuring temperature. One kelvin is equal to one degree Celsius, but theKelvin scalestarts at absolute zero and water freezes at 273.15 kelvin. ...
1.A unit of absolute temperature equal to 1/273.16 of the absolute temperature of the triple point of water. One kelvin degree is equal to one Celsius degree. See Table atmeasurement. 2.KelvinA temperature scale in which zero occurs at absolute zero and each degree equals one kelvin. Water...
The Kelvin scale of heat measurement differs from the Fahrenheit and centigrade scales in that it begins from absolute zero, the lowest possible temperature.Temperature Conversion FormulasThe temperature says how cold or hot an object surface or the object’s surrounding areas are. The temperature of...
Celsius is a temperature scale based on the freezing point (0°C) and boiling point (100°C) of water at sea level. Kelvin, however, begins at absolute zero, the theoretical lowest possible temperature, and has units the same size as Celsius degrees. 6 The Celsius scale is commonly used...

absolute zero - (cryogenics) the lowest temperature theoretically attainable (at which the kinetic energy of atoms and molecules is minimal); 0 Kelvin or -273.15 centigrade or -459.67 Fahrenheit temperature - the degree of hotness or coldness of a body or environment (corresponding to its molecular...
The exact values depend on the water composition (usually the amount of salt) and the air pressure.Seawater contains salt and the freezing point is reduced below 0 °C.When boiling water on a mountain above sea level the boiling point is reduced below 100 °C.The symbol of Celsius degrees...
The meaning of KELVIN is the base unit of temperature in the International System of Units that is defined by setting the fixed numerical value of the Boltzmann constant to be 1.380649 x 10—23 joules per kelvin and that is equal to 1/273.16 of the Kelvi
In low temperature studies, scientists prefer to use the Kelvin scale, which starts at absolute zero. 绝对零度等于华氏-460°或摄氏-273°,在这种低温之下,分子的能量减至最低程度,分子的运动亦差不多停止。 jw2019 In a stratified ocean of mean depth H, free waves propagate along coastal bounda...
