Temperature Of 2 17 K Superfluity
1,286 wordsCryogenics 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 kayos 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 temperature used, is the unattainable temperature -273.15 (C (-459.6...

Movie's Ice Age
1,054 wordsThe movie, The Day After Tomorrow, addresses the issue of global warming. The movie's portrayal of the events caused by global warming was extreme and not very believable. Some of the information is backed up by science but most is completely off the wall and non realistic. The movie cited the cause of the global climate change to be the rise in temperature due to greenhouse gasses. The warmer temperatures caused the polar ice caps to melt, and the increased amount of freshwater in the ocean dis...

Arctic Tundra
586 wordsTundra is the coldest of all the biome's. Tundra comes from the Finnish word, meaning treeless plain. It is noted for its frost-molded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons. Dead organic material functions as a nutrient pool. The two major nutrients are nitrogen and phosphorus. Nitrogen is created by biological fixation, and phosphorus is created by precipitation. Tundra is separated into two types: arctic tundra and alpine tundra...

Tundra Art Ic Plains
596 wordsThe tundra art ic plains completely covering most of the earth's lands north of the coniferous forest belt. The tundra's ecosystem is very sensitive. It doesn't have a good ability to restore itself. Controlled by sedge, heath, willow, moss, and lichen. Plains that are pretty much alike, called alpine tundra, occur above the timberline in the high mountains of the world. Even the Antarctic area has a couple of its own arctic regions itself. The climate of the tundra is characterized by harsh win...

Very Hard Phase In Steel
1,635 wordsPrinciples of Heat Treating of Steels A steel is usually defined as an alloy of iron and carbon with the content between a few hundreds of a percent up to about 2 wt%. Other alloying elements can amount in total to about 5 wt% in low-alloy steels and higher in more highly alloyed steels such as tool steels and stainless steels. Steels can exhibit a wide variety of properties depending on composition as well as the phases and microconstituent present, which in turn depend on the heat treatment. T...

Amylase At Extreme Temperatures
921 wordsAmylase and Starch experiment We took 3 trays, the name for the trays I have forgotten but they had about 12 small craters in each. We put a couple of drops of iodine into each crater. Then we took a syringe and filled it up to the 10 mark with starch solution, then, with the same syringe we sucked up a further 5 of amylase. We took a stopwatch and every 30 seconds we put a drop from the syringe into one of the craters and recorded the colour. To begin with, the resultant colour was black, indic...
