Lab Title: "The Effect of Salt on the Boiling Point of Water" Lab Question: How does adding salt to water affects it’s boiling point? Prediction : In this paper‚ a newly proposed model based on solvation between pure solvent and salt for prediction of salt effect on vapor–liquid equilibria is presented by using only the vapor pressure depression data of pure solvent+salt systems that compose the mixed solvent with salt system Materials : 200 mL of distilled water‚ 2 beakers

Does Television Violence Have an Adverse Effect on Children? Most people read statistics like "Before the average American child leaves elementary school‚ he or she will have witnessed more than 8‚000 murders on television" ( "Does T.V. Kill?" )‚ and worry about the negative effect viewing violence on television will have on their children. Research into the effects of childhood exposure to violent television programming shows that there is cause for concern. Watching violence on television

Boiling Point Lab Introduction: The purpose of this lab is to learn about the calibration of a thermometer. In addition‚ we also investigated the boiling point of an unknown liquid to determine its identity. Chemical Responsibility: 1. Make sure to use glycerine (lubricant) and a towel to safely insert the thermometer into the rubber stopper. 2. Carefully operate the Bunsen burner and make sure to use rubber gloves when handling the boiling water of beaker 3. Always wear goggles

classes average set of results by about 2‚ but‚ when graphing the alkalise by the boiling and melting point they both follow the same slope‚ it continues to rise just like the results gathered in the example do. 2. Which of the 2 unknown substances was which? How did you figure this out? The two unknown substances were the methanol and propenol because each of them were being tested in this experiment to discover the boiling point of each of these alcohols by analysing each of their temperatures to eventually

Does wind power have a negative impact on human health? By Kim Chau Contents page Wind power‚ how it works and how it’s used 1 Sound and the human ear 2‚ 3 Wind power‚ how it works and how it’s used Wind is the movement of air caused by difference in atmospheric pressures. Wind comes to many different uses along with many benefits; one of its greatest benefits is that it’s a renewable source of energy unlike materials such as coal and oil. The use of wind for energy also does not have

I expected‚ I found that it boiling point was 60C but in my experiment it was 30 C it’s the double of what it should be. Most of the sample like methanol and ethanol was pretty clos to the result that I found on internet. The trial that I did was Butanol again with the hot plates and it took of course much longer to boil and it started to boil before 105 °C like at 103 °C and I didn’t expect that happen maybe because of the boiling water it accelerated the boiling point. I don’t consider

Hypothesis: I think that in this experiment the results of the boiling point of each sample is going be slighly different from what I found on Internet. aim: my aim is to look at what temperature and how long the following alcohol (methanol‚ I-butanol‚ Ethanol and Hexane) reach their boiling point and comparing the results that I found on internet and mine. Materials: Alcohol: Ethanol‚ I-Butanol‚ Ethanol and Hexane Four Test tubes (boiling tube) Test tubes holder Data logger Hot plates Bunsen burner

Have you ever watched a drama that immediately submerges the audience in the opening scene? Yes? No? Shakespeare used this technique in Othello‚ but why? What effect does he want this opening scene to have on the audience? Keep them interested in his story. Of course‚ all composers and writers want their readers to read on‚ want to attract their attention‚ even Shakespeare. Shakespeare wants to put audience in the scene‚ in the play. Let the audience be a part of the play by submerging the

What is a reactive attitude? What bearing does it have on the problem of free will? A theory that has attacked the validity of discussions on freedom in modern philosophy is determinism. In these discussions‚ questions have arisen as to how the truth or falsity of this theory should affect our lives. In this essay I will discuss the formal implications‚ illustrated by Peter Strawson‚ that come about from this. This will mean discussion of our reactive attitudes on: our moral considerations and on

from the bed‚ she tiptoed through the boxes which lay everywhere and put a kettle of water onto boil. Waiting‚ she glanced over all her possessions‚ grateful she had the whole day before her. She scooped instant coffee into the cup and poured in now boiling water. Stirring the coffee‚ she tried to decide where to begin. She took a quick sip of coffee and searched her box of books. She ordered them neatly on a shelf. Then‚ she lifted her suitcase onto her bed. She unlatched the clasps and opened it and
