The problem of the ice melting The melting of polar ice is primarily caused by the increasing amount of gas emissions‚ mainly CO2 rising into the atmosphere (global warming) Global warming is the rise in the average temperature of Earth ’s atmosphere and oceans. Since the early 20th century‚ Earth ’s mean surface temperature has increased by about 0.8 °C. Scientists are more than 90% sure that it is caused by rising amount of concentrations of greenhouse gases‚ which are produced by human activities

Recrystallization and Melting Point of Benzoic Acid Organic Chemistry 1 10/4/12 Abstract Recrystallization was done to remove impurities from the sample. The percent recovery of benzoic acid during recrystallization is 23.02%. The difference between the pure and impure samples was observed by comparison of melting points. It was found that impure sample had a lower and wider melting point range of 120.1-122.2 (C). The pure sample melting point range was 121.3-122.5 (C). These ranges helped determine

"The Melting Pot Theory" In the 1800’s and the early 1900’s‚ some people gave the America the name‚ the melting pot. People imagined this because thousands and thousands of immigrants coming from around the world were coming into the United States in hope of a better life. So most people imagined that all these different cultures were being poured into a giant pot called America‚ heated to a low boil and molded into one kind of person. If one steps back and thinks about this theory‚ it isn’t

Fully Automated Highways Systems: Imagine a world where your car drives you and you don’t drive it! A world in which your car will take you any place‚ any time and all you have to do is sit there. This world is not so far away. The need for fully automated highway system development is in high demand due to the factors stated above. Fortunately‚ there is one such technology in the works‚ vehicle platooning; vehicle platooning is method used in AHS to increase the capacity of highways. The eight-vehicle

nvestigation into the Factor of Light and Dark Affecting Woodlice Predictions It was expected that a woodlice would prefer a damp‚ dark‚ but moderately warm surrounding. Normally one would expect to find slaters under logs or concrete slabs in one’s garden. Under these large objects‚ the sun cannot reach directly; therefore it is darker‚ damper and colder than the surroundings. Nevertheless‚ in winter we do not see woodlice crawling around very often‚ and‚ also at night‚ it may
