11, 2013 Title: Laboratory Techniques and Measurements Purpose: To gain knowledge about the International System of Units and use it to determine volume, mass, length, and temperature. To learn to use these forms of measurement to determine density and concentration, as well as learning basic lab equipment to create dilutions. Procedure: Part 1: After reading the various information given, I gathered different objects and measured them using both centimeters and millimeters then converted
30, 2012 1. Title: Laboratory Techniques and Measurements 2. Purpose: The purpose of this lab is to learn laboratory techniques and to how to measure precisely. During this lab I will learn how to measure length, temperatures, volume, density, and mass using laboratory equipment. I will be using laboratory equipment to prepare dilutions and calculate them while using an algebraic formula. 3. Procedure: In order to perform this lab I needed the following materials: a metric ruler
compaction test using standard effort on the same soil at different moisture contents. When the density of the soil is plotted over moisture content, a concave down curve is generated. This is because adding moisture increases density until it reaches its optimal moisture, then adding further moisture decreases density. Understanding the relationship between moisture and density is important because density is related to the strength of the soil. Procedure: Testing was done in Brookings, South Dakota
much solute is in a solution. In order to find the concentrations, both substances needed to be weighed and measured and finally have their data plugged into the appropriate formulas for molarity (mol solute/L solution) and density (m/v). To find the relationship between the density and concentration, a calibration curve was used. A calibration curve is a graph with a best fit line, revealing the connection between the two factors. Therefore,
atomic mass, corrosion, conduction. Density is a physical property; a measurement of how much matter is in the object. Yes, it is. All pure substances have their own individual characteristics in terms of density If the substance is heated and expands, then the density is going to go down because with a greater volume and no increase in mass leads to a lower density. The mass is 132g The density of the “silver” that is in question is 6.4 g/cm3 however, the density of pure silver is 10.5 g/cm3 Error
floating object will displace a volume of fluid if it has weight equal to the object that is floating. The primary purpose of this lab is to explore and demonstrate density. Density is defined as an object’s mass per unit volume, or essentially, a measurement of how close and tightly matter is crammed together within an object. Density can be found by dividing the mass of an object by its total volume. In this experiment, a grape and beaker of water were used to act out Archimedes’ principle by
contributed to the percentage differences over 5% in my opinion would be the purity of the fluid. For instance, after doing some research, I found that the actual density of glycerin is 1260 kg/m3, whereas the density obtained in the lab was 828 kg/m3, thus indicating that it probably was not pure glycerin. Being familiar with the formulas of density and unit weight of fluids is important as both values are necessary when it comes to calculating the pressure of the fluids in various regions. Thanks to these
Energy absorbed= volumetric energy density* volume =1/2*Y*volume*(strain)^2 (4) The volume is given by, volume= n m A c*dt (5) Here, c= Velocity of the sound in the armor material From equations (4)
Both hypothesizes can be combined to one; that if an area is high-severity, high pre-fire density, and logged (HHL) it will have a higher density than the high-severity, low pre-fire density, and logged (HLL). Methods The lands that burned during this fire were mainly comprised of a mixed-conifer forest. The main tree species found before and after the fire are Douglas- fir, grand fir, Pinus
vertical U tube of uniform cross section contains mercury in both of its arms. A glycerine (d = 1.3 g/cm3) column of length 10cm is introduced into one of the arms. Oil of density 0.8g/cm3 is poured in the other arm until the upper surfaces of the oil and glycerine are in the same horizontal level. Find the length of oil column. Density of mercury is 13.6 g/cm3. (9.6cm) 2. Two communicating cylindrical tubes contain mercury. The diameter of one vessel is four times larger than the
