Part I
1. Use the concepts/vocabulary of density to explain why the liquids formed layers in Part I of the procedure. (8 pts)
- Each liquid that was used in Part I has its own independent density. Density being the relationship between the mass and volume of a substance. In this portion of the lab we explored relative density, each liquid compared to the others. The corn syrup was the most dense, in comparison to the other liquids. Whereas the vegetable oil was the least dense compared to the other liquids. The liquids in between followed this same principle in their respective orders.
2. What was the control used during the liquid portion of Part I of this experiment? (8 pts) (Hint: What did you do the same with each liquid to ensure a fair comparison?)
- The control here was that we used the same amount of each liquid, 10mL, to ensure that the experiment was giving us a reasonable comparison.
3. Rank the following in terms of relative density: (9 pts)
Isopropyl alcohol (rubbing alcohol) 5
Liquid dishwashing detergent 2
Dark corn syrup 1
Vegetable oil 7
Glycerin 3
Rubber stopper 6
Cork stopper 9
Wood 8

2. What other factors did you need to control during your investigation? Explain how you controlled each one in your procedure. Factors that I needed to control in my experiment was the temperature of water, how many Alka-Seltzer tablets to put in, and how much water to use in the cups. I had a thermometer to make sure that when I done my two trials that they both had the same temperature of water, I only put one tablet per cup, and I made sure to have the same amount of water in each cup I used.…

A density column consists of layers of liquids of different densities which do not mix with each other, and which are clearly distinguishable from each other. The highest density material is at the bottom of the column, and as you proceed up the column, the density of each successive layer decreases, with the lowest density layer on top. Three methods for construction of a five-layer density column are discussed in this write-up. All methods use the same five liquids. • Method 1 gives the names of the liquids and the order for adding them, and its goal is to directly construct the density column without any experimentation. • Method 2 assumes names and densities of the five materials to be unknown, and involves open-ended experimenting, with few instructions, to construct the column. • Method 3 also assumes names and densities of the materials to be unknown, and outlines a systematic way to approach the experimentation involved in constructing the column.…

Density has been an important part of science for a very long time. Density was discovered by Archimedes, a Greek mathematician, around 250 BC while determining whether a craftsman had replaced some of the gold in the King of Syracuse’s crown with silver. Density is the compactness of a substance. The new concept of density he discovered was used to expose the fraud. The purpose of this experiment is to make the heaviest floating film container without having it sink. The density of water is 1, so in order to keep the film container from sinking, the density of the sand-filled film container must be less than 1. The equation for density is D=m/V, where m is mass and v is volume. To find the volume of the film container, use the equation V=3.14r^2h, where r is the radius and h is the height. My hypothesis is that if the density of the sand-filled film container is less than the density of water, then the film container filled with sand will float. But, if the sand-filed container does not have less density than the water, then the container will sink. The independent variable is the…

In this experiment, we have to measure the equivalent radius, bulk density and solid density of granular material. Granular materials are composed of grains or particles solids with interstitial spaces which is spaces between the particles. If the grains are small enough, the material is a powder. The solid density is the density of the material in the grains. It is important as it will determine whether the material will float or sink in water which the particle may or may not contain air. The bulk density is an important property, especially for storage and transportation rather than a separation process. It is defined as the mass divided by the total volume occupied by the material. This total volume includes air trapped between the particles. The volume fraction trapped between the particles is known as the porosity.…
