Liquid Nitrogen Surface Area
1,858 wordsIntroduction Background and Theory. Experimental Procedure. Results and Discussion Conclusions and Recommendations Nomenclature... References B. Equipment Diagram... The hydrogenolysis of ethane on a nickel on kieselguhr catalyst has only been conducted using a cylindrical pellet shaped catalyst of unknown surface area. We used a powdered version of this catalyst and compared its performance with that of the pellet catalyst. This comparison was conducted using one gram of catalyst in each reacto...

Nitrous Oxide Liquid Nitrogen
551 wordsNitrogen was isolated by the British physician Daniel Rutherford in 1772 and recognized as an elemental gas by the French chemist Antoine Laurent Lavoisier about 1776. Properties Nitrogen is a colorless, odorless, tasteless, nontoxic gas. It can be condensed into a colorless liquid, which can in turn be compressed into a colorless, crystalline solid. Nitrogen exists in two natural forms of isotopes, and four radioactive isotopes have been artificially prepared. Nitrogen melts at - 210. 01 C (- 3...

Degrees Celsius Mothers Womb
2,134 wordsAs we enter a new millennium we are also making vast technological improvements. In the field of medicine in particular, there is cause for great optimism. There has never been more power to restore, maintain and extend health. However there is something even bigger approaching, cryonics. Many people think of cryonics as some futuristic, science fiction process that would only be possible in the movies. However the idea of cryonics isn t really that unreal. There are many groups and scientists w...

People In The United States Liquid Nitrogen
1,594 wordsFrom the time theyre born, human beings are driven by an impulse to take things apart and put them back together. A small group of maverick scientists have decided to take this process one step further. Their project, called cryonics, aims to take apart and reassemble the worlds most complicated machine: the human body (Epstein 16). Cryonics is the practice of freezing human bodies in the hope that one day, it is possible to revive these people and restore them back to health. Although this idea...

Liquid Nitrogen Degrees F
890 wordsSince the beginning of time people have been trying new ideas for keeping things like food cold. Up until the early 20 th century ice was the best method for cooling perishable items, button we figured out a more efficient and affective way of keeping items cold. It was called the refrigerator. Soon after the introduction of the refrigerator we developed something called cryogenic freeing, which is freezing with very low temperatures. Cryogenic freezing is the study mater that is colder than tem...

Carbon Dioxide Liquid Nitrogen
2,011 wordsPURPOSE: In this particular laboratory experiment, we are going to determine the molar mass of an unknown gas, from the gas density. We are also going to use gas density, along with the kinetic molecular theory, to explain the behavior of gas filled balloons. Finally, we are going to demonstrate the effects of temperature and pressure changes of gasses. PROCEDURE: We are using the experimental procedure as described in our laboratory manual. University of Wisconsin River Falls Laboratory Manual ...

Liquid Nitrogen Liquid Hydrogen
1,519 wordsCryogenics and the Untitled Cryogenics and the Future Cryogenics is a study that is of great importance to the human race and has been a major project for engineers for the last 100 years. Cryogenics, which is derived from the Greek word keys meaning " Icy Cold, " is the study of matter at low temperatures. However low is not even the right word for the temperatures involved in cryogenics, seeing as the highest temperature dealt with in cryogenics is 100 (C (- 148 (F) and the lowest te...
