    Melting pointe determination #01 Introduction: Objective To learn how to obtain an accurate melting point using a MELTING POINT APPARATUS‚ then use them to draw eutectic curve and determine the eutectic point. Melting point of a solid is the temperature at which the solid and its liquid form are in equilibrium‚ i.e.‚ molecules move back and forth between the two states at the same rate‚ so both phases remain present. If the temperature of a solid is measured carefully as the solid is heated

    Melting Ice Caps The Arctic is global warming’s canary in the coal mine. It is a highly sensitive area which is profoundly affected by the changing climate. The average temperature in the Arctic is rising twice as fast as elsewhere in the world (nrdc.org). Because of this‚ the ice cap is getting thinner‚ melting away‚ and rupturing. Here is an example of this; the largest ice block in the Arctic‚ the Ward Hunt Ice Shelf‚ had been around for 3000 years before it started cracking in 2000 (nrdc

    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 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

    8. a) The melting of the ice sheet in greenland may bring opportunities for people and communities rather than a negative threat. One advantage of of the melting ice sheet may be that it brings in a better income for people. Melting ice sheets means that more land is being uncovered exposing expensive rocks and riches such as zinc and lead. The reveal of land and rock means that people and communities are able to mine this will give people a better income and lifestyle. Mining can be done in all
