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

in humans (Caplan‚ 286). The most well known experiments in this regard were the experiments conducted on twins at Auschwitz. The other goal of the Nazi scientists was to provide human data that could be applied to the war effort. Experimentation of this sort mainly probed the extremes‚ which the human body could tolerate in a hostile environment. The most famous experiment of this sort was the Dachau Hypothermia Study.’ The rationale of the experiments was as follows: "A consequence of air combat

the 1960’s‚ around the time when Martin Luther King Jr. was fighting for civil rights for people of color‚ a 3rd grade school teacher‚ Jane Elliot‚ from Riceville‚ Iowa was busy at work in an attempt to recreate the negative emotional and physical effects of racism within her classroom. She created an experiment in which she divided her students into unequal groups as a way of creating artificial stereotypes‚ prejudices‚ and discrimination. Jane Elliot eventually expanded her experiments into the

of sound in air through the pulse-echo experiment and the measured air temperature. Hypothesis: I believe the measured air temperature will affect the speed of sound because sound waves are longitudinal waves composed of the alternating compressions and rarefactions in air. If the air temperature is below 0°C‚ then the speed of sound would be lower than 331.6 m/s and if the air temperature is above 0°C‚ then the speed of sound would be higher than 331.6 m/s.
