    9/23/12 Lab Report #1 Meter Reading Summary The objective of this experiment was to learn how to read different meters like the D.C. volt meter and the D.C. amperes meter. In all meters each big line is a major division and each little line in between is a minor division‚ and if there is a line smaller than the minor division lines then that would be a sub minor division. Each meter has a low‚ medium‚ and high range. For example on the D.C. volt meter the ranges go from top to bottom 150‚ 15‚

    Results: Since the mass of the ball bearing used in this experiment was very light‚ 20 balls were measured and the result was divided by 20 for better accuracy. This procedure was repeated for the sizes and the results are as follows: Diameter (mm) Mass (kg) 2 0.04 3 0.075 4 0.11 To find out the densities of the three balls‚ the following formula was used: Density= (mass of the ball)/(Volume of the ball)= mass/(4/3 π r^3 ) Density of 2mm ball = (0.04⁄1000)/(4/3 π 〖(0.001)〗^3

    Introduction The aims of the lab session was to familiarize with the principles‚ operation and application of a light spectrophotometer. This report discusses an experiment to study the relationship of absorbance and concentration‚ the interaction of electromagnetic radiant energy(ERE) and matter which is an important aspect of the Beer-Lambert ’s Law. This law states that the absorption of a compound is directly proportional to the concentration of that particular compound. This is because (a &

    during the lab session Procedure Part A This lab was performed by the group members as they closed both low and high flow rotameters (Fig-2) and filled the tank with water. Then‚ the large rotameter was opened when the water in the tank had reached the internal baffle‚ so the flow from the tank was reduced by doing so. One member was in charge of adjusting the level of the water so it was always maintained over the baffle’s level during the lab (Fig-1). The first part of the lab was done
