Every winter road salt is used on sidewalks‚ roads‚ and highways to melt snow and ice. These are to prevent human activates from turning into accidents. When the snow melts the road salt gets dissolved into the melted ice and snow and becomes a formula. This formula sinks into the land (soil mostly) and kills vegetation. The purpose for this exit project experiment is to find out what are the affects of road salt on plants. The reason for doing this lab is to find out what a

Polymer Essay: Plexiglass Many of the glass screens and windows we see today are not really made of glass. They are made of plexiglass. Plexiglass is not related to the chemical structure of glass at all. It is an organic polymer. Today this polymer is used in all sorts of applications. The formation of plexiglass was begun in 1930‚ at McGi11 University by William Chalmers‚ a research student. He polymerized methacrylic ethyl ester and methacrylic nitirile‚ creating a clear plastic paste

The Cambodian Genocide happened in 1975 when the Cambodian government was taken over by the Khmer Rouge. Millions of people were killed and evacuated to labor camps where they were abused and starved to death. Even though all of this was happening in Cambodia‚ no other countries came to help take back the government. Why would other countries step aside when a country is in desperate need? The Cambodian Genocide was during the time of the Vietnam War. This war is what started the regime

WRITINGS OF PLAUTUS In Plautus’ plays The Haunted House and The Pot of Gold Plautus tells stories of families staged during the ancient times in Athens. Throughout the plays Plautus depicts the Roman society. Giving insight to many Roman social concerns such as women‚ and women rights‚ how important politics were to the Romans‚ slavery‚ and father son relationships. Throughout Plautus’ writings it is very evident that women in the Roman society were to stay home cook‚ clean‚ manage the household

Are We a Melting Pot or Salad Bowl? Are We a Melting Pot or a Salad Bowl? Unless an American citizen is a Native American‚ he or she is part of a great country filled with immigrants. Those who came before us‚ our ancestors‚ came here from every corner of this small world. There was a time‚ and it was not so long ago‚ when America’s motto was “give us your tired and weak” etc. We embraced immigrants that sought a new life here. That‚ however‚ is no longer the case as the problem of

Essential Question: How did Pol Pot’s envisioned “New” Cambodia‚ “Year Zero Project” transform Cambodia then and what effects does it leave in Cambodia today? What is the background/history of the genocidal conflict? The Cambodian genocide was the leader of Khmer Rouge‚ Pol Pot’s idea to restore the country agriculturally by deconstructing cambodia back to a primitive “Year Zero”. The idea of Year Zero arose in the 1950s after the French decolonization and devastated the region until the late 1980s

amount of heat required to convert a mass of a solid at its melting point into a liquid without an increase in temperature. As difficult as this may sound‚ this experiment can be carried out with minimal equipment. The following equipment was needed‚ a 100mL graduated cylinder‚ a calorimeter‚ a digital thermometer‚ a calculator‚ water‚ and ice cubes. Procedure: The procedure to find the heat of fusion for ice was measured by melting ice cubes in a known volume and temperature of water and carefully

habitat is melting at a rate none have expected to be so quick‚ leaving there less to enjoy. Why is the ice melting? I believe it is global warming‚ although some might debate my beliefs. I believe that the rapid change in temperatures caused by the increase of C02 Admisions is rapidly raising the temperatures of the polar bears habitat. Some argue that‚ we have only tracked a 1 degree temperature change throughout the earth‚ that is a mere change that would not send the ice melting so fast‚

This experiment shows how one determines the temperature-composition diagram for a two-component system. The procedure will consist of obtaining cooling curves for the pure substances and a number of their mixtures. A cooling curve is constructed by melting a sample‚ then allowing it to cool‚ measuring the temperature at regular intervals. When only melt is present‚ there is a constant cooling rate. As the solid begins to form‚ the system remains at a constant temperature until the melt is completely
