Calorimetry Lab Report Waris Butt PHY 112 Mr. Fasciano Class #18336 06/08/14 Purpose: Heat flow will occur between objects in contact until no more heat flow is detectable. Using calorimetry to analyze heat flow quantitatively and the equation: Q = mc ΔT‚ to determine the specific heat capacity of an object and heat flow from or to an object; respectively. Materials: Circle K 44 oz Styrofoam cup with lid Large Plastic

Experiment 13 Charging and Discharging Capacitors 1. Introduction In this experiment you will measure the rates at which capacitors in series with resistors can be charged and discharged. The time constant RC will be found. Charging a capacitor. Consider the series circuit shown in Fig. 1. Let us assume that the capacitor is initially uncharged. When the switch S is open there is of course no current. If the switch is closed at t=0‚ charges begin to flow and an ammeter will be able

technique is: Number Moles Concentrated Solution = Number Moles Dilute Solution. An instrument called a spectrophotometer detects the amount of light that passes through the sample and the percent transmittance can be recorded from the meter. In the lab‚ multiple homogeneous solutions are made. There was not a way to determine the differences in concentrations‚ but the Spec 20 made it possible to measure the difference. The Beer-Lambert Law is a graph used to record

Physics 1 Lab #10 1/29/13 Chapter 7 Lab:Pop Rockets 1. List and explain two ways that you could improve the flight performance of your rocket. Your responses must consider the materials you had available to work with. The rocket I produced was a normal looking rocket compared to the group of rockets I was working with. It was medium size in length and thickness. The head of the rocket was a little wide and lose‚ and the flaps were not arrow dynamic what so ever. To improve the flight

Osmosis Lab Report Hypothesis: Osmosis will occur when there is an uneven distribution of solute in a solvent. The higher the solute in solvent‚ then there will be a higher rate of osmosis through the diffusion gradient forming a hypertonic or hypotonic solution. Solvent with equal or no solute forms an isotonic solution. Materials: Distilled water‚ sucrose‚ dialysis tubing‚ string‚ 250 ml beaker. Procedure: To demonstrate and isotonic solution we needed 3 inches of dialysis tubing. We

Corte Madera Scientific Report Abstract I examine how rising or falling tide can affect the water level of Corte Madera Salt Marsh in this report. The data is from Wednesday (June 19th) and Thursday (June 20th). My hypothesis is that tide and water level have positive relationship. From the result‚ I learn that the water level and tide have positive relationship. However‚ when tide changes its direction‚ the water level is likely to stay or little change. Introduction On June 19th‚ my

Synthesis of Tetraphenylcylopentadienone Post-Lab Report Purpose- This experiment illustrates the use of adol condensation for the synthesis of a five-membered carbocylic ring. It is also a good demonstration of the impact extended conjugation has on the absorption of visible light. The reactants are bright yellow in color while the products are a very deep purple color appearing almost black. Introduction- The synthesis of Tetraphanylcyclopentadienone was a further example of the adol

Alhia Harris October 18‚ 2011 Biology Lab report Proteins are very important throughout the body. They have a lot of functions in cells. Antibodies are proteins that help cells rebuild the cells when they are destroyed. Transport proteins move substances from one place to another. Regulatory proteins control cellular metabolism in a way that cells throughout the body can have the right amount of glucose in the blood. A common protein is an enzyme; in cells they speed up chemical reactions. For

Unknown Lab Report Microbiology Unknown A Sonia Kabra November 26‚ 2014 Introduction There are numerous reasons for identifying unknown bacteria. Some of these organisms have distinct qualities that set them apart from one another‚ such as the exposure to certain environments. Through out the semester in the laboratory‚ we are able to encounter some of the few microorganisms that we as humans have come into contact with. With the knowledge gained from the sessions in the laboratory‚ we can now

Unknown Lab Report Dr. Nathan Cahoone Microbiology 204 December 9‚ 2010 Introduction There are many reasons for knowing the identity of microorganisms. The study and test was done by applying all of the methods that have been learned so far in the microbiology laboratory class for the identification of an unknown bacterium which I was using unknown #25. Results Unknown #25 had the following morphology on a streak plate: medium sized butyrous cream colored colony. Gram-staining was utilized
