Density: A Characteristic Property I Purpose The purpose of this experiment is the density of six different substances. The way to figure this out is by finding the mass and volume of each of the substances. The hypothesis for the different experiments is that with each of the different substances and mixtures will be different depending on what they are. II Equipment The late nite lab was used to conduct this experiment. The product used were a balance, a graduated cylinder, water, Ethanol, and unknown liquid, Iron and an unknown metal. III Procedure There were four different small experiments to look at density. In experiment 1 a balance was taken and put to zero. Then a 50 mL graduated cylinder was put on the balance. The mass was …show more content…
Density is the ratio between the mass of an object and its volume. The equation for density is Density= mass/volume. Mass is the measure of matter that an object obtains and volume is the space that the object occupies. In these experiments, through the balance and graduated cylinder the mass and volume were measured for the different substances. As it was clear to see each of the different substances had different masses and volumes which means they had different densities. In experiments 1 and 2 they show that the water was denser than ethanol but the known liquid was denser that water. In experiment 3 the density of water and iron is shown and through experiment 4 it shows that iron is denser that the known metal. Through these different experiments they show the different densities …show more content…
For example, usually the solid form of a substance is denser that the liquid form but water is an exception. In reality, when water turns into a solid its density decreases by 9 percent. This is very critical for any sea creature for if ice was denser than water then if the body of water they were living in froze they would freeze with it. Thankfully God knew this and he made it so when the water froze the ice would float to the top creating a blanket causing the water underneath not to freeze allowing the fish to live. Another example of density is in a helium balloon. A helium balloon floats in the air because its density is less than water causing it to float in the air. Scientist could further look into density in many ways. They could try to figure out in what other substances would their solid state float in their liquid state like water. They could also do some experiments on water to try to figure out why ice is less dense than water. In these experiment, there could have been some errors with the calculation of the densities of the substances but hopefully these errors were minor and did not make a different

If we were given a random sample of pennies, then we could measure the mass and the volume of the pennies. From these measured values we could calculate the density. Then we could compare our calculated density to the given density value of copper and we could find the the percentage of error between copper and the measured density. Conclusion: If the percentage of error between the copper and the measured density of the pennies was large and the values were not in comparison to the density of copper, then we would know that the density of a penny is not the same as the density of pure copper.
On our paper we predicted the amount of pennies that could fit in the boat before it sank. We tested the boat in the water and added pennies one by one. We then calculated the mass of pennies that fit in the boat and the density of it. The purpose of this Lab was to make a boat that holds as many pennies as possible and understand how to calculate
In this week’s lab we had to determine the density of a quarter, penny, and dime. My question was “How does is each coin?” Density is the amount of mass in an object. To find the density of each coin in this lab, we used a triple beam balance to find each coin’s mass and a graduated cylinder to find their volumes. With all this information, I can now form a hypothesis.
Objective The foremost purpose of this laboratory experiment is to comprehend notion of moles and Avogadro’s number; and also to grasp the idea of converting among mass, moles, and number of atoms in a sample (Hammerschlag 1). Importance Pace University Professor Carroll Zahn allocated a novel assignment to his introductory computer class, in which the results of this assignment greatly astounded both the professor and his class. The subsequent description that was stimulated by the unanticipated results of this miraculous event is the inspiration for the following case study. Perplexing his class, Professor Zahn told them to calculate the cost of a single aluminum atom in a roll of aluminum foil that he had recently purchased.
However trying to comprehend science can be to some extent vague. First in order my science experiment fundamentals are about how dense can the fog get using different variations on how much water I am going to use to make fog along with the dry ice. The science experiment is going to use a mix of materials. First of
Purpose The purpose of this lab was to utilize a series of tests that would determine the different properties of the tap water and oil. Density was measured using the mass of a liquid in a known volume, the specific gravity was determined by using a hydrometer, and viscosity was measured by using the weight of a falling mass to spin a cylinder completely submerged in the test fluid. The values determined from these tests could then be compared to known values to viscosity and density. Theory
The different state of matter (solid, liquid, and gas) have different properties. • This difference could be explained based on how individual atoms or molecules are held together in a matter. • The following table summarizes properties of solids, liquids, and gases, and identifies the microscopic behavior responsible for each property.
Average density in general is determined using the formula mass divided by volume. Therefore, the two properties needed to determine the density of a planet are the its mass and volume. What makes finding the average density of a planet interesting is the way astronomers have to go about finding the planet's mass and volume, as you cannot simply place a planet on a scale. In order to determine the mass of a planet, Kepler's Law is used. By determining the period of its moons' orbits, they are able to determine the planet's mass.
After the experimentation, you may ask yourself “Why did all of these spheres fall at a different rate when Galileo said that objects fall at the same rate (in a vacuum)?” The reason why the objects fell at a different rate in the fluids given was because the fluid’s viscosity varies. The viscosity of a fluid can impact an object that you drop into it, because there’s a resistance of some sort impacting the rate of which they fall. For example, when both spheres were dropped at the same time into a graduated cylinder of water, the steel sphere hit the bottom of the graduated cylinder before the glass sphere, because the viscosity of water is low. The viscosity of water is very dynamic based on the temperature, but both of the spheres were denser
It’s measured by calculating mass/volume (D=m/v). Objects made of the same material will have the same density regardless of their volume. Density is an intensive quantity and is independent of
In the last activity (of the curriculum), students are supposed to be creating new boats out of aluminum foil paper. Even though we will not have students performing this activity, the sixth activity of the curriculum allows student to experiment with density as they are presented with new materials. As they are supposed to be creating new boats out of aluminum foil paper, they are experimenting with different densities in comparison to their clay
Figure ( 1 ) shows the XRD for bismuth borate glass samples containing molybdenium oxide from 0 to 20 mol %. From figure (1) can observe that the samples containing molybdenium oxide up to 15mol%MoO3 are in the amorphous state. Then the sample containing 20mol% MoO3 are I the amorphous and crystalline state. The analysis of the sample containing 20mol% MoO3 poured between two copper plates or poured at air, the x-ray diffraction patterns indicate the formation of Bi2MoO6 crystalline phase formed in the sample at air more intensity than the sample between two copper plates. This phase is one of the important Aurivillius oxides  possessing special perovskite-like layer structures, photocatalytic activity under visible light irradiation, the increased optical absorption efﬁciency and the decreased photo-generated carriers recombination efﬁciency.
4.2 Physical Analysis 4.2.1 Density Test Table 4.1 shows, the samples of undoped calcium phosphate pellets using various sintering temperature. From the experiment, different sintering temperatures are used such as 1000ºC, 1100ºC and 1200ºC. Each sintering temperature have five samples are being used to measure the density of the samples. After analysis, the average density will be collect and recorded.
When an object is not dense, it will float which will make the atoms loose. Scientists are able to measure density by dividing the mass of an object and dividing the object by its volume. Overall, density is the amount of mass in a given space. Variables: Independent Variable: Different Amount Of Salt (Mass in Grams) Dependent Variable: Density of Salt Solutions (Layering of Solutions)
