properties of gases enables one to predict their values under given conditions. Learner Outcomes Upon completion of this laboratory activity, the student should be able to use the pressure probe to carry out experiments with gases. determine the relationship between the pressure and the volume of a gas. Background This experiment will draw upon your experience with computer-based laboratory methods from previous lab activities utilizing the computer. In the first part of the experiment, you will see how

example, severe Vitamin C in a prolonged period can lead to scurvy. Vitamin C can be obtained from fruit, vegetables, and lab made Vitamin C tablets. The synthesis of Vitamin C supplements in the laboratory was found to be extremely efficient in 1933. They are now largely manufactured in laboratories and sold to the market. However, degradation of Vitamin C occurs over time. The rate of degradation will be accelerated when exposed to air, light, and heat. Therefore, it is essential for the manufacturers
Sample Formal Laboratory Report for Physics on the Picket Fence Lab (CP) without the parachute Purpose: The purpose of this experiment is to verify the acceleration due to gravity using the picket fence with a photogate, LabPro and LoggerPro software by measuring it with a precision of 0.5% or better. Theory: All objects, regardless of mass, fall with the same acceleration due to gravity assuming that there is no air resistance. Objects thrown upward or downward and those released from
square root of length of string and the length of suspension, (i.e. ｄ ). Although discrepancy is found when the equation proposed by eminent scholars is compared against with ours, our findings can hardly pale into insignificance as errors and the cause of uncertainty are discussed and ways to improve the experiment are suggested, which can possibly spur further studies on this realm of knowledge. I. Introduction In physics, there are mainly two ways from which useful equations can be derived. One
personnel, laboratory facilities, equipment, and reagents were discussed. Before embarking upon the actual analytical work, however, one more tool for the quality assurance of the work must be dealt with: the statistical operations necessary to control and verify the analytical procedures (Chapter 7) as well as the resulting data (Chapter 8). It was stated before that making mistakes in analytical work is unavoidable. This is the reason why a complex system of precautions to prevent errors and traps
Chemistry [Laboratory Techniques and Measurements] Date Submitted: March 15, 2013 Date Performed: March 14, 2013 Lab Section: Chem-181DL1 Purpose The purpose of this lab is to learn about the International System of Units (SI). This is to help with the familiarity of common laboratory equipment and techniques. Also to help with determining the volume, mass, length, and temperature of a variety of items using common laboratory measurement devices.
Copper-Iron Stoichiometry Lab Report 10/3/12 Abstract: The lab performed required the use of quantitative and analytical analysis along with limiting reagent analysis. The reaction of Copper (II) Sulfate, CuSO4, mass of 7.0015g with 2.0095g Fe or iron powder produced a solid precipitate of copper while the solution remained the blue color. Through this the appropriate reaction had to be determined out of the two possibilities. Through the use of a vacuum filtration system the mass of Cu was
past century have made accurate measurement of many different properties essential. We wake up to electrical alarm clocks, cook in microwave ovens, and regulate the heat in our homes with thermostats. These devices depend on accurate voltages, currents and resistances to function properly. Metrology [1] is the science of measurement, providing accuracy we need to succeed in business and our personal lives. It is within metrology, that definitions for measurements are agreed upon. Calibration is
