Relative density

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

We designed an investigation to find the answer to the question ‘How does the height of a marble affect the work it does on the cup?’ The question explores how the height has an affect on the amount of work done on the cup and the amount of gravitational potential the marble has. We tested this by creating an experiment in which we dropped a marble down a ramp to hit and move a cup while testing the different heights we collected the data of how far the cup moved and used it to create a trend and

Determining the Density of a Polystyrene Sphere with Precision and Accuracy Abstract: The objective of the lab is to determine the volumes of the polystyrene spheres with three different measuring tools: Water Displacement, Analytical Scale, and Triple Beam Balance Scale. The experiment is meant to help understand the concept and application of precision and accuracy in experimental measurements. Accuracy is a measure of how closely the results of repeated measurements are to the true value of what

Objective: My objective for this experiment is to find the mass, volume, and density of a variety of objects. After this, I will record my data and place a select few of the items on a graph. My hypothesis for this experiment is, "If I measure the mass of every object, the wooden ball will have the least because it seems to be the smallest and most lightweight. " 2. Equipment: 3 rubber stoppers, 5 rocks, wooden ball, wooden cube, 4 density cubes, triple beam balance, graduated cylinder, pipette, and beaker

Using the collected data, the rate of water loss from the sand needs to be calculated using the psychrometric chart and the change in weight of the sand mixture over time. To illustrate the process of calculating the water loss, the equilibrium data from Trial 1 will be used. T_(wb,out)=24.5⁰C T_(db,out)=50.5⁰C T_(wb,in)=23.5⁰C T_(db,in)=50.5⁰C With the wet and dry bulb temperatures, the psychrometric chart was used to find the moisture contents and humid volumes for the air at the inlet and outlet

Results and Conclusions: Density measures the mass of substance per unit of volume. Density of solids is measured in grams/cM3. Density of liquids is measured in grams/mL. Density of gases is measured in grams/Liter. Specific Gravity is when the density of many substances are compared are compared to the density of water which is 1 gram/cM3. If a substance has a density less than 1 gram/cM3, it will float but if the density is greater than 1 gram/cM3, it will sink

Are the Volumes of Pure Substances Additive? Introduction In this lab, the densities and mass of water and isopropyl alcohol were calculated in order to answer the question ‘are the volumes of pure substances additive?’ This lab was used to help introduce the different types of glassware that will be used, as well as basic concepts such as density and the difference between accuracy and precision. Accuracy is how close the measure value is to the true value, while precision is how close the measured

From this lab, we can learn how using the volume and mass of an object can be used to the calculate density, and how the density can help you to identify what substance the object is made of. We began the lab by obtaining object C and recorded the physical properties of the substance. Next, the object was placed onto a scale to determine the mass in grams (56.56g). We used a ruler to measure the radius of the base (.6cm) and the height (5cm) of the cylinder-shaped substance. We plugged these measurements

Introduction To provide the client with the needed information regarding the material used on site, several tests were ran to determine if the roadbed material meets all of the requirements as stated in the Wisconsin Department of Transportation (WisDOT) 2016 Standard Specifications, Part 3, Section 301 and 305. The material has been identified as a ¾” dense graded crushed stone base aggregate. The sampling, aggregate properties, specific gravity, and sieve analysis were completed according to

Introduction In order to identify new materials, scientists use a variety of chemical and physical methods to determine molecular masses. One of these methods includes the Dumas method for determining the molecular weight of a volatile liquid. This method, which was proposed by John Dumas in 1826, makes use of a volatile liquid (vaporizes at a relatively low temperature) and allows this liquid to be heated in a water bath to a known temperature and escape from a flask through a tiny opening (Giunta
