Charles Lindbergh Shortly after Charles Lindbergh landed‚ he was swarmed by 25‚000 Parisians who carried the wearied pilot on their shoulders. They were rejoicing that Charles Lindbergh‚ the American aviator who flew the first transatlantic flight‚ had just landed at Le Bourget field in France. Having just completed what some people called an impossible feat‚ he was instantly a well-known international hero. Despite his pro-German stance during World War II‚ Charles Lindbergh is also an American

Trial # Guess Observation Explanation Trial 1 The dyed red water will not seep into the blue cold water. My guess was indeed correct and red water did not interfere with the blue water. Because the molecules in the blue water are much closer together because its cold and well the red water has warm/hot water and the molecules are everywhere. The molecules in the blue water are so dense that they’re making a layer so that the molecules from the red jar do not come through. Trial 2 I think

(1) Answer to Question in lab manual. NO introduction/background etc. 1. What is the retention time for caffeine? Retention time for caffeine : 4.149+4.142+4.152+4.1454 = 4.15 2. What is the retention time for benzoic acid? Retention time for caffeine : 2.651+2.817+2.857+2.9274 = 2.81 3. How are the retention times for caffeine and benzoic acid related to their chemical structure and the nature of the chromatographic

Discussion: Conclusions: • For both meters it was noted from plots that the difference in pressures are directly related to the rate of discharge. • Coefficient of discharge have a varying value depending on the rate of discharge‚ where in the Venturi meter the value of Cd increase gradually at first with increasing the rate of discharge till a point approaching one‚ then started to descend with further increment in the rate of discharge. • The Coefficient of discharge " Cd

Experiment 7 General Safety Considerations 1. 1-Butanol and 1-bromobutane are toxic and irritating. Avoid all contact by constantly wearing goggles‚ gloves and working in the hood. Neither of these compounds can be poured down the drain. Like all products‚ 1-bromobutane should be turned in to your TA in a labeled vial. Any excess butanol should be discarded in non-halogenated waste. 2. H2SO4 is extremely corrosive. In very diluted form it can be poured down the drain‚ all other precautions

Charles Edward Spearman (1863-1945) studied psychology in Germany and received his PhD at Leipzig. Spearman is noted as a pioneer in psychology and believed in the two-factor theory of intelligence. He wrote his first paper outlining this theory in 1904 with Bernard Hart (Gregory‚ 1987). Spearman claimed that testing a persons abilites to complete tasks against expected outcomes could be measured and expressed in a mathemactical formula‚ that mathematical formula is now known as the Tetrad Equation

Story Dr. Heidegger invites to his study four elderly friends to engage in an experiment. Three are men: Mr. Medbourne‚ Colonel Killigrew‚ and Mr. Gascoigne; the fourth is a woman‚ the Widow Clara Wycherly. The study is a dusty‚ old-fashioned room replete with a skeleton in the closet‚ a bust of Hippocrates‚ books and bookcases‚ and a portrait of Sylvia Ward‚ who died fifty-five years before the night of the experiment on the eve of marriage to the doctor after swallowing one of his prescriptions

Investigation: The Stanford prison experiment was originally intended to run for a fortnight. However it lasted only 6 days and was ended earlier than initially planned due to the terrible living conditions and psychological problems that developed as the ‘inmates’ and ‘guards’ interacted.. The experiment was run by Philip Zimbardo‚ Craig Haney‚ David Jaffe‚ and W. Curtis Banks. The test subjects were young male college students that were chosen from 75 volunteers. The volunteers had replied to

Experiment 5 Polytropic Expansion of Air Object The object of this experiment is to find the relation between pressure and volume for the expansion of air in a pressure vessel – this expansion is a thermodynamic process. Introduction The expansion or compression of a gas can be described by the polytropic relation ‚ where p is pressure‚ v is specific volume‚ c is a constant and the exponent n depends on the thermodynamic process. In our experiment compressed air in a steel
