The purpose of this experiment is to examine the densities of different liquids, such as soft drinks and water. This experiment will help us answer the question, “which among these liquids has the greatest density?” The data collected from this experiment will be analyzed to compare the densities of these liquids. In using the Archimedes’ Principle, this experiment will seek to examine the density of liquids rather than solids. This experiment will explore the area of physical science and applying it to everyday objects.

When terms of measurement such as mass, weight, density, and volume are thrown around in science, their meanings can become confusing. Many people often associate weight with how much stuff that the object

This would most likely be because of human error in measuring out the liquids, since a graduated cylinder was not used, or because of incorrect measurement. The graphs represent that trial one has the Diet Coke set with the lowest density and regular Coke at the highest with about 1.034 g/cm3. In trial two, the regular Coke still has the highest density, but the water became the lowest. So the liquid that has the lowest density could either be the water or Diet Coke since they have the lowest densities among the graphs. In the line chart they both seem to rise and fall in mostly the same areas, however trial two’s line has higher values. The main purpose of this experiment was to find the densities of different cokes and compare them. Not only was that accomplished, but the answer to another question was answered - what soda is more dense and the answer is Coke. The original hypothesis was regular Coke, Diet Coke, Dr. Pepper, Pepsi, and last is water. The tested out experiment gave this information - Coke, Dr. Pepper, Pepsi, Diet Coke, and water. The data that contained the two different volumes of the liquid proved that the density that the liquid had not changed much, but it did change to a certain extent. That change is shown in the line chart that compares the first trial and the …show more content…
In the beginning, the hypothesis made was Coke, Diet Coke, Dr. Pepper, Pepsi, and water. After conducting this experiment, the data showed that the answer is: Coke, Dr. Pepper, Pepsi, Diet Coke, and water. In order to conduct this experiment the liquids needed to be measured for mass and volume, once that was completed the variables could be plugged into the equation - d=m/v. This experiment not only explored the area of physical science, it applied physical science to everyday objects. It proved that the density between sodas are different, even if by a tiny amount. Something to do differently in the next trial would be to get a graduated cylinder to replace the measuring cup. In this way the scientist would not experience any mistakes or errors in the process, since it is less likely for human error. This experiment has given the answer to the hypothesis and helped to show what density
I am doing this experiment to find the density of aluminum foil to see if it floats or sinks when placed in water. I hope to find how the density of aluminum foil changes when weight is added to the foil. I hypothesize that the boat will hold 20 pennies before sinking.
It was learned that changing the volume of the same substance will never change the boiling point of the substance. However having two different substances with the same volume will result in two different boiling points. The purpose of this lab was to determine if changing the volume of a substance will change the boiling point. This is useful to know in real life because if someone wanted to boil water to make pasta and did not know how much water to

It was then placed in the ice bath, in which immediately the can slightly collapse on itself. In part two of the experiment, the prepared ice bath temperature measured at 1°C (T2). While the heated bath temperature stabilized around 85°C (T1) after 5 minutes, where it also began to simmer. The test tube with the rubber stop in the heated bath had no water for the entire 5 minutes. When the test tube was placed inside the ice bath for 5 minutes water appeared to flow inside the test tube. The amount of water that flowed into the test tube measured at 5 mL (Vw). When determining the volume of the test tube in the 100 mL graduated cylinder with 30 mL of water, it displaced the water up to 74 mL. Thus determining the volume of the test tube as 34 mL
I am going to carry out an experiment to measure the change in mass of
Regarding the densities of Coke and Diet Coke, I believed that the density of coke would be greater than the density of Diet Coke. Because the content of Coke contains more sugar than Diet Coke, it would contain more mass and since density is mass dependent, Coke would be denser than Diet Coke. From the results of the experiment, there was a slight difference between the densities of Coke and Diet Coke. The measurements obtained from the pipette and the graduated cylinder demonstrated that Coke is denser than Diet Coke while Diet Coke was shown to be denser than Coke using the burette. With the pipette, the average density of Coke is 1.02 and the average density of Diet Coke is 0.99. With the graduated cylinder, the average density is 0.976968 and the average density of Diet Coke is 0.95. With the burette, the average density of Coke is 0.99 and the average density of Diet Coke is 1.0. Among the three instruments, the most precise was the graduated cylinder and the most accurate was the volumetric pipette. Since density is defined as mass/volume, changing the volume of Coke or Diet Coke would have changed.
In a Styrofoam cup, record the temperature of the 200 ml of cold water. This is 200 g of water, as the density of water is 1 g/ml.
There are many ways to examine the subject of alchemy, including alchemy as a source of symbolism, psychology, and mysticism. It has also been an influence on the world view of various writers, artist, and musicians. The focus of this report is alchemy as a pre-chemistry, which gave a new impulse towards the preparation of medicinal remedies and also was a major influence on today's scientific investigations.Alchemy is an ancient art, practiced in the Middle Ages. The fundamental concept of alchemy stemmed from Aristotle's doctrine that all things tend to reach perfection.
Part A of the experiment, we were measuring the density of water. In this part, we measured by difference by measuring the mass of the empty graduated cylinder which was 46.35 grams and then added 25.0 milliliters of water to it. When subtracting by difference, our mass of the water was 25.85 grams. This was close to the measurements of the water added to the graduated cylinder. The density of the water was 1.0 grams/milliliters.
Generally pycnometer is made of glass, with a clos-fitting ground glass stopper with capillary tube through it, so that air bubbles mas escape from the apparatus. This device enables a liquid density to be measured through an appropriate working fluid, such as mercury or water, using analytical balance. When the flask weighed empty, full of water, and full of a liquid whose relative density is desired, then relative density can be easily calculated. The specific gravity results show that subsoil specific gravity varies between 2.45 and 2.7. Pycnometer analysis work system shown in Figure 12.

Operation: A hydrometer is a measurement instrument used to measure the relative density of liquids, the ratio of a density of a liquid to the density of water.
Density, by definition, is mass per unit volume. In the case of fluids, we can define the density (with the aid of Fig. 1.3) as the limit of this ratio when a measuring volume V shrinks to zero. We need to use this definition because density can change from one point to the other. Also in this picture, we can relate to a volume element in space that we can call “control volume,” which moves with the fluid or can be stationary (in any case it is better to place this control volume in inertial frames of reference).
