How Table Salt Affects the Boiling Temperature of Water Essay Example

How Table Salt Affects the Boiling Temperature of Water Paper What hypothesis can you generate about the effect of adding salt to water? Adding table salt to boiling water will cause the water to boil at a higher temperature. Experimental Design List the materials used in this lab, and the procedure you followed. Materials: 1 . Kitchen stove or electric hot plate 2. One 2-cup measuring cup 3. Measuring spoon set, with one tablespoon maximum 4. Table salt 5. Tap water 6. 2 quart cooking Pot (1/2) i dont have sorry 7. One digital thermometer Procedure (list steps in the order in which you performed them): 1. Boil one quart of tap water on stove. . Measure the temperature of the boiling water. Record highest temperature reading. 3. Add the measured salt to the boiling water and stir. 4. Measure the temperature of the boiling water with the salt in it. Record the highest temperature reading. 5. Repeat this process the second time with 2 spoons of salt and the third time with 3 spoons of salt. Data Record the data you collected in the lab. (The data table and the graph. ) Table 2. Boiling point temperatures of various salt solutions. Beaker/ Concentration of Nasal (M) Boiling Point Temperature Pure tap water 100. (00 1 tablespoon salt solution 102 (CO) tablespoon salt solution 103. 5 (CO) 3 tablespoon salt solution 105 (CO) Graph the data from Table 2 Label each axis (X and Y will NOT do). Devise a scale for each axis and label that scale (1, 2, 3 ) Plot the data points. Connect the data points by drawing a straight line. Title the graph. Analysis Analyze the data you collected in the lab. How does the data presented above relate to the hypotheses you generated earlier in lab? Are any hypotheses disproved by your experiment? Use your graph to determine the boiling point of a solution made with 2 h tablespoons. This use of a graph has generated a hypothesis that a 2 h tablespoon solution boils at 104 degrees C. Prepare a 2. 5 M solution and verify your hypothesis. The data i presented above relates very well with my hypothesis i generated earlier in my lab that, if i add table salt to the boiling water it will cause the water to boil at higher temperature. So my hypothesis was approved by my experiment. If i was to boil with 2 h tablespoons of salt, the boiling water would reach 104 degrees C according to my graphs data. Also according to my hypothesis that stated overtime you add more table salt the higher the temperature will go.

Be sure to base your answer on the data you collected. If you are given a solution of unknown concentration, can you determine its concentration? Explain. i wouldnt describe my problem i raised when i described the purpose of the lab any different way. i say this because when i described the problem it helped me figure out a good hypothesis, which was if i add table salt to the boiling water it will cause the water to boil at a higher temperature. Thus, i conducted a successful experiment which proved that adding more and more table salt to the boiling water does increases the temperature. Thus, because of the idea of the problem it gave me a successful experiment and hypothesis. Additional questions for this lab: Notebook Activity: How do you apply the scientific method in everyday life? List examples. Notebook Activity: Conversions between units If there are 1000 meters in a kilometer, how many meters are there in 0. 05 km? 50 meters. If there are micrometers (pm) in a meter, how many pm are there in one millimeter (mm)? 1000 pm If an object is 334 pm wide, how many mm wide is it? 0. 334 mm. If we have one Liter of a solution, how many millimeters (ml) is that? 1000 ml Did your TAP water boil at 100 degrees C? If not, what might account for this? No, mine was close though it boiled at 100. 5 C. i think this happened because The tap water most likely did not boil at exactly 100 degrees Celsius because tap water is not pure H2O. There are other impurities in it that would affect the boiling point. An experimental control is a test that lacks the experimental variable. Was one of the solutions prepared in this lab a control? If so, which one? Yes, the tap water being boiled at a 100. 5 C that receives no added table salt is the experimental control. In our experiment, you controlled one of the factors. Which one (temperature or Nasal concentration) was it? i controlled the Nasal concentration. This factor was the independent variable; it was controlled by you, the experimenter. The other variable was a consequence of changes you made. This is the dependent variable. It was a consequence of changes in the independent variable. What factor (temperature or Nasal concentration) was the dependent variable? Temperature was the dependent variable.

The Lion In Winter essays

The Lion In Winter essays The Reality of the Medieval Soap Opera The Lion in Winter begins with a friendly sword fight between father and son, a lively jousting match, and a battle led by King Henry IIs son, Geoffrey of Brittany. All scenes are typical of the 12th century. A few mistakes did exist, however, which included reference to syphilis, pulp paper, and Christmas trees. Despite minor errors, the greatest historical accuracy lies within the portrayal of the royal families of England and France. Both families are uniquely connected and utterly dysfunctional, which is characteristic of many soap operas today. Henrys sons are continuously fighting over the throne and plotting with the enemy, the king of France, Phillip II Augustus. Meanwhile, Queen Eleanor is constantly instigating arguments over the children, his mistress, and their marriage. Henry IIs children are notoriously known for their misconduct and rebellion. Following Henrys eldest sons death, brothers Richard, Geoffrey and John fight competitively to be heir to the thrown. One of The Lion In Winters major themes is the family tension that exists over Henrys heir. The film accurately grasps the character of the brothers desire to acquire the crown. For example, there is a scene where each brother seeks out Philip II Augustus, the king of France, in order to create an alliance. All three are caught red handed when Henry surprises them all with a visit to Philip. Richard, known as the Lionheart, has been built up in history as a constant soldier and sometimes poet. The picture adheres to this description. Richard states his loyalty to his fathers kingdom by refusing to give up Alix or the Aquitaine if he becomes king. Furthermore, Richards softer side is revealed by means of his apparent love affair with Philip. This follows historical belief that Richard Lionheart was a homosexual. Like his brother,...

Causes and Trends of Homophobia in Middle East Essay

Causes and Trends of Homophobia in Middle East - Essay Example It is really an escalating tug of war between the homophobic society, human rights activists, and homosexual oriented persons. Undeniably, the Middle East society has been adamant in supporting lesbians, gay bisexual and transsexual (LGBT) groups since time immemorial. What is the status of homophobia In Middle East? This paper addresses the current issues of homophobia in Middle East by trying to answer the following important questions. What are the current trends of homophobia in Middle East? What are the main causes of homophobia in this region? Current Trends of Homophobia in Middle East Homophobia refers to the outraged fear and expression of anger towards homosexuals or simply to people who express sexuality that differs from the normally accepted heterosexual behavior or identity. Since time immemorial, the general society has always recognized and appreciated the heterosexual type of orientation towards sexual identity. However, few societies have identified and developed their own sexuality identity. Middle East has been in particular very resistant towards any persons or group of people deviating from heterosexuality. For the last few years, increased homophobia has been observed in Middle East. It is claimed â€Å"In parts of Africa, the Middle East, the Caribbean, and elsewhere it is still very dangerous to be gay. People are being executed. Homophobic attacks, rapes, and murders happen all too frequently† (Dehgan, 2011, p. 1). Homophobia has always been suppressed by various societal structures such as the law, traditions, and religion. Most Middle Ea st countries have laws that prohibit marriage between homosexuals or any other form of sexuality besides heterosexuality. For instance, â€Å"More than two dozen men were arrested at what police called a â€Å"mass homosexual wedding† in the United Arab Emirates† (The Advocates, 2006, p. 37). However, as the society becomes more revolutionized more homosexuals come out in the opens and begin fighting for their rights. This is arguably the main cause of homophobia in this region and the rest of the world as well. Many people are coming up in the open to form groups that help them express their concerns on how the society treats them due to sexual orientation. The media plays a very important role in shaping the discourse of issues affecting the society. In the Middle East, media influence is a great force that cannot be ignored. Arguably, it has given the two opposing camps a fair playground in expressing their feelings and opinions. Homosexual groups come out in the me dia and openly express their stand towards sexuality. Internet and television has been one of the most widely used media in which homosexuals use to either express their sexuality or express their outrage against groups fighting them. Middle East countries are mostly Islamic. This implies that there is high degree of homophobia in this region than any other region in the world. Islam religion strictly prohibits homosexuality and has stern disciplinary measures and actions against homosexuals. Koran prohibits this type of sexuality and as such, Muslims in this region use it as a source of authority to discredit homosexuality. Politicians play a role in shaping the societal fabric. Politicians have been known to follow the current trends and demands of the population to achieve their political ambitions. Arguably, the politicians have been instrumental in quenching the homophobia crisis by advocating for equal rights to people of all types of sexual orientation. It has enabled the soc iety to accept the homosexuals and their sexual orientation rather than fighting them. Indeed, there is a slight increase in countries accommodating homosexuality. Habib agrees that â€Å"
