Ideal Gas Law Lab 1. Procedure: First‚ we used a balance to weigh the canister of gas‚ and recorded that mass as the original weight. Then‚ we filled a large bucket with water and recorded the temperature. We then filled a small test tube with water at the same temperature and poured that water into a graduated cylinder to measure the original volume of water in the tube. We then poured the water back into the test tube and placed the tube into the bucket with the opening upwards‚ turning the

Preparation of SKEO The extraction of S. khuzistanica was performed by hydro distillation and clevenger apparatus for 5 hours. Once extraction was completed‚ the resulted essential oil was dehydrated using sodium sulfate (Merck). The essential oil was stored at temperature of 4ºC until using (12). In order to provide different concentrations of the extract‚ Dimethyl sulfoxide (DMSO) was used. Gas chromatography/mass spectrometry analysis of essential oil Isolation and measurement of the sample

Alixandria Zeidel Physics 131 – section LZ Hasbrouck 208 10/01/14 Forces and Newton’s 2nd law Abstract The purpose of this lab was to learn about how force influences acceleration. A hanging mass is tied to a frictionless glider and the mass is dropped. While the glider is being pulled by the mass it is possible to measure to tension force on the rope between the two objects. A motion sensor graphs the movement of the system and from the slope it is possible to calculate the acceleration of both

Senan Farrelly Alec Haas Introduction Ohm’s Law is V = I * R or in some cases I = V / R. The next two laws were established by a German physicist by the name of Gustav Kirchhoff. Kirchhoff’s first law is his voltage law. Kirchhoff’s Voltage Law (KVL) states that around any loop in a circuit‚ the voltage rises must equal the voltage drops. The next law that Kirchhoff introduced was his current law. Kirchhoff’s Current Law (KCL) states that the total current entering a junction must equal the

Research Paper – Georg Ohm Georg Ohm was a German physicist born in March of 1789. Georg came from a Protestant family. His father who was a locksmith Johann Wolfgang Ohm‚ and his mother who is Maria Elizabeth Beck‚ was the daughter of a tailor. Even though his parents had not been really educated at the time‚ Ohm’s father was a very wise man who had educated himself and his son Georg. In my research I found out that he wrote an elementary grade geometry book while teaching mathematics at

have XL=XC and the impedance‚ Z is equal to the resistance R‚ where Z=R. Because the capacitative and inductive reactances vary with the frequency of the AC current‚ the impedance of a circuit containing capacitors and inductors also varies with AC frequency. For a circuit with AC current flowing at angular frequency ω‚ its impedance is given by where XL = ωL is the inductive reactance‚ XC = 1/ωC is the capacitative reactance‚ R is the resistance‚ and ω = 2π f ( f is the linear frequency).

because there was more mass to pull as more books were added. This shows newtons 1st law because the books wanted to stay at rest‚ but as more force was added they moved. The 2nd law is seen because the more mass there was‚ the more force was required to accelerate the books. The 3rd law is there because as you pull on the spring balance‚ it pushes pulls back on you‚ which lets it move. The eggs connect to the first law because the hard boiled egg is easier Egg 1 mass: 60.6 to start and stop‚ but the

GEORG SIMON OHM Georg Simon Ohm (16 March 1787 – 6 July 1854) was a Bavarian (German) physicist and mathematician. As a high school teacher‚ Ohm began his research with the new electrochemical cell‚ invented by Italian scientist Alessandro Volta. Using equipment of his own creation‚ Ohm found that there is a direct proportionality between the potential difference (voltage) applied across a conductor and the resultant electric current. This relationship is known as Ohm’s law. Ohm died in Munich

This lab report will be detailing the steps taken and the results discovered when using spectrophotometry to determine the percentage of copper in a copper-clad penny and the thicknes of the copper layer on the copper-clad penny. After 1982‚ copper coating has been used in the creation of the penny because the cost of pure copper has increase to the point that the amount needed t omake a penny cost far more than the actual value of the penny. This lab allowed us to see just how much copper coating
