cryogeny and the Future         Cryogenics is a take in that is of dandy importance to the kind race and has been a major spew for engineers for the last blow years. Cryogenics, which is derived from the Greek word kryos meaning Icy Cold, is the study of matter at low temperatures. However low is non even the respectable word for the temperatures involved in cryogenics, see as the highest temperature dealt with in cryogenics is 100 (C (-148 (F) and the lowest temperature utilize, is the unrealizable temperature -273.15 (C (-459.67 (F). Also, when speaking of cryogenics, the hurt Celsius and Fahrenheit are rarely used. kind of scientists use a different measurement called the green (K). The Kelvin scale for Cryogenics goes from 173 K to a fraction of a Kelvin in a higher place commanding zero. There are also two briny sciences used in cryogenics, and they are Superconductivity and Superfluidity.         Cryogenics first came virtuall y in 1877, when a Swiss Physicist named Rasul Pictet and a French coordinate named Louis P. Cailletet liquified oxygen for the first time. Cailletet created liquid oxygen in his lab using a process known as adiabatic expansion, which is a thermodynamical process in which the temperature of a flub is expanded without adding or extracting heat from the gas or the mite system(Vance 26).
At the same time Pictet used the Joule-Thompson Effect, a thermodynamic process that states that the temperature of a fluid is reduced in a process involving expansion below a certain temperature and pressure(McClintock 4). subsequent on Cailletet and Pictet, a third method, kn! own as cascading, was highly-developed by Karol S. Olszewski and Zygmut von Wroblewski in Poland. At this point in account oxygen was now able to be liquefied at 90 K, then soon after liquid atomic number 7 was obtained at 77 K, and because of these...
