Density Essays

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

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

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

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

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 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

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

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

Determining Smallest Possible Charge on Droplet Using Millikan Oil Drop Experiment Simulation Abstract: The purpose of this lab was to determine the value of the smallest charge using a Millikan oil drop simulation on the TI-83+ graphing calculator. This was done by using a program on the TI-83+ graphing calculator, where an oil droplet was placed on the screen and cursor keys were used to adjust the voltage until the droplet is suspended. The droplets radius, voltage, plate separation

7-1: How does balance impact visual weight? Balance refers to the even distribution of weight in a composition. In artwork that is a sculpture and architecture, the actual weight is material in pounds or kg. In visual weight, the apparent “heaviness” or “lightness” of the shapes and forms arranged in the composition. The visual balance in composition by three ways—symmetrical balance, asymmetrical balance or radial balance. The first type of balance is symmetry; there are several symmetrical balances

Access the “Why do things float?” interactive from our Physical Science webpage. It is listed in the “Unit 2” section in the middle column Read the sidebar information on the left side of the screen and answer the following questions in complete sentences on your graph paper: What is the buoyant force? The buoyant force is the upward force that opposes gravity. What is the buoyant force equal to? The buoyant force is equal to the amount of water it displaces. How does Archimedes’ Principle explain

In the “Candy Waterfall” project, the effects that size and shape have on the rate of mass flow are tested through the use of multiple different granular materials going through a funnel. In lower grade levels students are taught about the three types of matter: solids, liquids, and gases. What are not explained are materials like sand: you can stand on sand like a solid, but you can also pour it out of a bucket like a liquid. Materials like sand are known as granular materials. By testing the rate

Spiritual Truths about Surface Area and Volume All objects have a certain amount of volume. They also have their own surface area. These two geometric terms have their own unique formulas. The formula for the volume has special formulas for different objects. The equation for volume of cylindrical figures is V=A(B)*H; of conic figures is V= ⅓ A(B)*H; of spheres is (4/3)()(r3). The formula for the surface area has various equations for different objects. The equations for surface area of objects

DENSITY is a physical property of matter, as each element and compound has a unique density connected with it. Density defined in a qualitative manner as the measure of the relative "heaviness" of objects with a constant volume. For gases the density may amount with the number of gas molecules in a constant volume. Helium balloon: Compare the behavior of helium filled balloon with that of an air filled balloon. Even taking into account the weight of the rubber balloon, the helium balloon floats
