what is cryogenics?

Answer 1

Cryogenics is a branch of physics (or engineering) that studies the production of very low temperatures (below –150 °C, –238 °F or 123 K) and the behavior of materials at those temperatures

Answer 2

Cryogenics is a branch of physics (or engineering) that studies the production of very low temperatures (below –150 °C, –238 °F or 123 K) and the behavior of materials at those temperatures

Answer 3

Cryogenics is the study of very low temperatures or the production of the same, and is often confused with cryobiology, the study of the effect of low temperatures on organisms, or the study of cryopreservation. Likewise, cryonics is the nascent study of the cryopreservationof the human body. Unlike cryogenics, cryonics is not an established science and is viewed with skepticism by most scientists and doctors today.

Answer 4

Cryogenics
The branches of physics and engineering that study very low temperatures, how to produce them, and how materials behave at those temperatures. Besides the familiar temperature scales of Fahrenheit and Celsius, cryogenicists use the Kelvin and Rankine scales

The field of cryogenics advanced during World War II when scientists found that metals frozen to low temperatures showed more resistance to wear. Based on this theory of cryogenic hardening, the commercial cryogenic processing industry was founded in 1966 by Ed Busch. With a background in the heat treating industry, Busch founded a company in Detroit called CryoTech in 1966. Though CryoTech later merged with 300 Below to create the largest and oldest commercial cryogenics company in the world, they originally experimented with the possibility of increasing the life of metal tools to anywhere between 200%-400% of the original life expectancy using cryogenic tempering instead of heat treating. This evolved in the late 1990s into the treatment of other parts such as musical instruments, baseball bats, golf clubs, racing engines, firearms, knives, razor blades, brake rotors and even pantyhose. The theory was based on how heat-treating metal works (the temperatures are lowered to room temperature from a high degree causing certain strength increases in the molecular structure to occur) and supposed that continuing the descent would allow for further strength increases. Using liquid nitrogen, CryoTech formulated the first early version of the cryogenic processor. Unfortunately for the newly-born industry, the results were unstable, as components sometimes experienced thermal shock when they were cooled too fast. Some components in early tests even shattered because of the ultra-low temperatures. In the late twentieth century, the field improved significantly with the rise of applied research, which coupled computers to the cryogenic processor in order to create more stable results.

Cryogens, like liquid nitrogen, are further used for specialty chilling and freezing applications. Some chemical reactions, like those used to produce the active ingredients for the popular statin drugs, must occur at low temperatures of approximately -100 °C. Special cryogenic chemical reactors are used to remove reaction heat and provide a low temperature environment. The freezing of foods and biotechnology products, like vaccines, requires nitrogen in blast freezing or immersion freezing systems.

Answer 5

Cryogenics is a branch of engineering that related to study of production of very low temperatures (below –150 °C) and the behavior of materials at those temperatures. it all about achieving it.

Answer 6

Cryogenics and cryology represent a branch of physics that studies very low temperatures and their effects. The prefix "cryo" comes from the Greek word "kryos," which means extreme cold. The suffixes "genics" and "logy" come from the words for "producing" and "study" ( methodical). When you put them together, you get the words "cryogenics," and "cryology," the production of very low temperatures and the study of their effects.

In outer space, things may get very hot, then very cold. This is an important factor in the design and choice of materials for spacecraft.

Answer 7

Freezing a human body just after death in the hopes that sometime in the future people will be able to reverse the process. Unfortunately, freezing the body causes all the cells in the body to lyse (Burst). (Just like when you put a soda can in the freezer).

Answer 8

Freezing someone until a later time.

Answer 9

related to extremly low temperature physics

Answer 10

Its freezing a biological speciment for later use.
