Abstract: This report presents the reason why the ocean does not freeze in the winter. Since the ocean consists of salt water‚ an experiment was done to test the effect of freezing on salt water compared to pure water. The experiment was conducted three times in order to obtain accurate results and eliminate errors. In addition to the salt and pure water experiment‚ a variation of this experiment was created to test other options. In the variation experiment the effect of freezing on sugar water

Physics Lab Report#3 “Determining the period of a pendulum” Name: Fei Huo Date performed: October 1st‚ 2014 Period 5 Teacher: Mr. Glasel Purpose: The Purpose of this Lab was so that my classmates and I can examine what kind of factors affect the period of a pendulum. Introduction: In a simple form‚ the pendulum is a weight hung from a long string that Galileo discovered that it can be used to track the passage of time very accurately around 400 years ago. In this

Introduction The Disbursement Acceleration Program of the Aquino Administration should not be implemented because it does not contribute in the GDP and economic growth of the country‚ although it may have been partially successful‚ its rediscovery has drawn reaction as “Unlawful”‚ aside from being unconstitutional‚ it does not serve‚ neither its spending was translated to over-all increase of jobs‚ nor trigger a downturn in poverty incidence. II. Background The Disbursement Acceleration Program (DAP) is a

Raquel Johnson October 19‚ 2014 Solids: Recrystallization and Melting Points Organic Chemistry 2423 Lab Report: Recrystallization Abstract: The purpose of this lab was to purify an unknown compound by recrystallization. Taking an unknown compound and identifying it by purifying it from its impurities through the use of hot gravity filtration. Then to determine the unknown you were to take the melting point. An unknown compound was recrystallized from hot water to produce 0.99 grams (67% recovery)

Synthesis of Butyl Benzoate Using Phase Transfer Catalysis The objective of the experiment is to synthesize the butly benzoate by nucleophilic substitution and characterize it by IR spectroscopy. The percent yield of the final product is determined after the synthesis. Procedures: 2.0 mL of 1-bromobutane‚ 3.0 g of sodium benzoate‚ 5.0 mL of water‚ 4 drops of Aliquat 336‚ and a boiling stone were placed in a 50mL round-bottomed flask. The reaction mixture was refluxed for 1 hour and the flask

org/go/Experiment_480.html Pendulum Motion Aim: To determine the rate of acceleration due to gravity by using a pendulum. Background Information: Equation One: T=2πlg Where T = the period of the pendulum (s). This is the time taken for the pendulum to return to its starting position. l = length of the pendulum g = the rate of acceleration due to gravity (ms-2) * In order to find the acceleration due to gravity‚ the equation must be rearranged to look like this‚ and give “g” as the subject:
