Density Essays

In this lab, we were trying to figure out the density of unknown metals. We determined the density at the end by first measuring the mass of the metal on a scale, then using water displacement, finding the volume of the metal. First, we decided to use metal B. We took out one piece of the metal and measured the mass by placing it on the scale. Then, we filled up the graduated cylinder with exactly 20 mL of water. After filling up the cylinder, we gently placed the metal inside and recorded the

The Density Exploration lab called for us to use two different methods to calculate the density of copper with various shapes and sizes. The second experiment called for us to devise an experiment to calculate the differences in density between soft drinks. Rather than calculating using two different methods to calculate for the same substance we had two different soft drinks, diet and non-diet Coca-Cola. We then used two volumetric pipets to measure the volumes of the soft drink, then placed the

OBJECTIVE The purpose of this experiment was to measure the density of an unknown metal object and use the measured density to insinuate a probable identity for the metal. PROCEDURE In part one of this experiment, an unknown metal object, a graduated cylinder, water, and a mass balance was first collected. The object was dried with a paper towel to avoid any water droplets and the mass balance was checked to read 0.0 g when nothing was on it. The first measurement that was retrieved as the mass

September 23, 2014 Penny Density Lab Introduction Using pennies in an aqueous solution demonstrate the simple use of mass and volume required to understand the measurement of density. The purpose of this lab is to understand density’s’ significance. The density of a substance is a physical property and can be discerned by its homogeneous separation of levels with substances of differential densities. Determining density does not require any chemical or constructive processes. Density is the ratio of a substance's

the water to 24.0 mL, thus the metal object was 3.0 mL for measurement 2. In a graduated cylinder of 21.0 mL, the metal object raised the water level to 23.9 mL, thus the object was 2.9 mL for measurement 3. The density of the metal object was then calculated using the formula density equals mass divided

The data used from the experiment that supports the hypothesis was that the floating film canister density was 0.47 g/mL3 and it was the least dense out of the three. The floating film canister represented the crust of the Earth. The suspended film canister represented the mantle and it had a density of 0.80 g/mL3. The sunk film canister was representing the core for this experiment and it had a density of 1.34 g/mL3. Based on the data collected, that the more sand you add to the film canister, the

INTRODUCTION Density, mass divided by volume, is one of the most important characteristic of matter (Sciencing) since it affects whether objects will float or sink, thus making it hugely important for the workings of the universe and in daily live (Sciencing). All objects have density and that density can increase or decrease as the result of actions taken on the object (Sciencing), such as adding salt into a substance like water, as has been done in this particular experiment. When salt is dissolved

mixing. However, the phenomenon occurring is indeed possible! Density plays a key role in layering water. Density is basically the state of being compact, and can be changed by factors such temperature or dissolved salt. There are some real-life examples in nature where water is blanketing water, and the layers are not blending with each other. This may appear as an effect of putting together water with different salinities. Salt, density, and temperature play essential roles to impacting the traits

figure out the identity of the rock based only on its density and physical properties. With an experimental process, one will begin to compare and uncover the identity of the rock samples brought back. To begin with, is the experimental process used to determine the identity of the rock. In doing so one will need to discover the density of the rock. By measuring the rock sample with grams per milliliter is a way used to figure out the density. In starting one will need to measure the mass of the

increase while the density of the gummy bear would decrease after it is put into water overnight. (#)This lab experimented to figure out wah changes would take to the gummy bear’s mass, volume, and density after sitting in a cup of water overnight. To do this the gummy bear's dimensions and weight was taken on the first day, along with its density and then the gummy bear was placed and water. When the gummy bear was taken out of the water on day two, the dimensions, weight, and density were taken again

average density through the help of the displacement method. Furthermore, the purpose of this lab was to identify the substance of the materials being tested, which in this case were a variety of pennies along with an unknown substance. In addition, the procedure being followed to get precise results focuses on calculating the mass of your substance followed by the volume of that same substance by using the displacement method which leads to calculating the density. Afterwards, the densities of each

Slope Slope = y2 - y1x2-x1 = 57.47 - 18.7460 - 20 = 38.7340 = 0.96825 g/mL The density graph has been based off all the information in the chart above. All the specific volumes and masses were recorded in this graph, in order to help compare the two and see the difference. In addition to this, a trendline was added in order to calculate the slope of the line. The slope line is a representation of the change in density overtime. More specifically, it shows the change of value in the mass of the water

The Cartesian diver was named for the French philosopher and scientist René Descartes, who invented this marvelous experiment. The main science behind this experiment is Density. Density is simply how much mass a certain material has for a volume that is given. In other words, how tightly packed and object is. Two ways that density could be increased is by adding mass to an object without changing its volume, or by keeping the mass the same, and decreasing the object’s volume. Objects will only sink

to figure that out. Well the thing that makes something float is called density. Density is the weight or mass something has. The weight of salt is the ocean if it was in sodium chloride would be about 120 million tons. Which got me wondering about how much would make an egg float. This floating happens because of all the different masses. Mass is mostly based on how many atoms a substance has. Mass also helps determine density. Another thing mass also determines is volume. The more the mass the more

The big ideas of Teacher’s Guide for Clay Boats: Experiments with Floating, Sinking, and Simple Volume Relationships curriculum are displacement, density and buoyancy. Displacement happens when an object is fully submerged in a liquid, pushing it aside and taking its place. Students are exposed to displacement in the first activity of this curriculum. They are able to observe this as a piece of clay is placed into lukewarm water. The clay pushes the water aside as it begins to sink. Buoyancy is the

the idea of density. Density is the amount of cmpactness in an object. We used oil and water, and observed the density of each substance. when pouring the two back and forth, the oil moves slower and the water moves faster and more choppy then the vegetable oil. Seeing this, oil was presumed to be more dense, so I made a hypothesis that if testing the density of oil and water, oil is more dense than its counterpart of water. After a trial of both, it turns out that water has a density of 0.96 g/ml

accurate something is, and it shows which place value is the estimated one if/when used correctly. In this lab, the density for water that was found is 0.99g/mL and the percent error was 1%, and 1% is good. An error that could have occurred while finding the density for water was that the measurement were not exactly correct because not everything is going to be perfect. The density for Copper that was found was 8.5g/mL, and the percent error was 5%, and 5% is fair. An error that occurred during

The slight increase changes in mass were due to the increase of pennies. The property of density which is independent of the amount or size of the material used to find out what actually caused the change in mass. The slope of linear fits for the mass and volume graph gives us the average density for the pennies. The hypothesis was accepted because the data supports that the more pennies added increased the volume. The laboratory experiment

Graph 12: Plot of Process Capability for Weight Percent Solids. Conclusions for Part D (Graphs 7-12): • Lube density is proportional to viscosity and weight percent solids. • Temperature will affect the viscosity and weight percent solids. o About halfway through the shift the lube will drop in viscosity from the heat. When the viscosity first drops, the weight

urine temperature, urine volume, calculate specific density, urine pH and urine flow rate. After the calculations are done, the subjects will use the Labstix strips to measure if their urine tests positive or negative for blood, ketones, glucose, and protein. In my hypothesis I will expect water to have the greatest urine volume and flow rate, then all other drinks (Gatorade, Coke, and non-drinkers). Non-drinkers will have the highest specific density out of all other drinks, both Gatorade and Coke will
