结果1 题目 8. The unit of temperature that is mostly used by the science world is called . A.Celsius B.Kelvin C.Volume D.Fahrenheit 相关知识点: 试题来源: 解析 B 科学世界(研究中)使用最多的温度单位标准是开尔文(Kelvin),其优点是没有负值,绝对零度被定义为0K. 反馈 收藏 ...
The Kelvin scale of temperature uses the same increments as the Celsius scale, which is to say that a change of 10 Kelvin is the same as a change of 10 degrees Celsius. This is due to the conversion between Kelvin and Celsius: C = K - 273. This scale was created in 1848 and is ...
A. Conductor (C)a semiconductor (D) a m B. a Conductor C. a semiconductor D. a metal E. or a semiconductor material, at zero degree in Kelvin temperature, the resistance across it is ( ) F. 0Ω G. 100Ω 10Ω ∞ semiconductor andgap energy Eg=1.14eV,maximum energy of a valence...
1. Kelvins 0°K is the lowest temperature possible. Particles have no kinetic energy. It is used by scientists. 2. Celcius The absolute zero temperature is -273°. It is used in most other countries. It is expressed by the symbols °C. ...
The kelvin is a unit of measurement for temperature; O K is absolute zero, thetemperature at which all thermal motion ceases. Conversion from Fahrenheitto Kelvin is given by K=5/9 × (F-32) + 273. The average daily temperature inMonrovia, Liberia, is 78.35F with a standard deviation of...
W/mK translates to Watts per meter Kelvin. Without going into it with big words, etc :- Watts is the power (in this case a power to be moved related to heat) I think you know what a meter is Kelvin is a temperature measurement (in this case it refers to a movement in temperature...
热力学第二定律,开尔文的说法是___The Second Law of Thermodynamics, according to Kelvin, is this___ A. 理想的热机是造得出来的,从单一热源吸热使之全部做功,这样的热机造得出来的;The ideal engine can be made by absorbing heat from a single heat source and doing all the work; B. 理想的冷机...
The temperature of boiling water is 100___. A. degrees Celsius B. degrees Fahrenheit C. kelvin D. radians 相关知识点: 试题来源: 解析 A。水的沸点是 100 摄氏度。“degrees Celsius”是“摄氏度”;“degrees Fahrenheit”是“华氏度”;“kelvin”是“开尔文”;“radians”是“弧度”,都不符合水的沸...
The Kelvin temperature scale is anabsolute temperaturescale with zero atabsolute zero. Because it is an absolute scale, measurements made using the Kelvin scale do not have degrees. The kelvin (note the lowercase letter) is the base unit of temperature in the International System of Units (SI)...
