prisms, and one cube to make a pair of glasses for the two Ping-Pong ball model. We choose these shapes because, we both knew how to find the surface area and volume of them to the point where it wasn’t easy, but it was not super difficult. We felt safe using these shapes. When put together they also can be taped together perfectly to resemble a pair of glasses. We thought that this would be a great model to make because, for one thing my partner and I both wear glasses so we thought that it would be a fun, familiar, and a creative model to make to house our Ping-Pong balls. It's also a very creative idea, and not a bland idea. For our second model we chose to make a more simple model which is a cylinder. We chose this idea because, even though it is not the most fun model to look at, it is also very convenient. The Ping-Pong balls would fit perfectly in it, and you can stack the balls on top of each other. They would be easy to take out, and they would be organized. This is why we choose the cylinder model for our four Ping-Pong ball model. My partner and I worked together through our words, rather than grabbing, or yelling. We also assigned jobs to each other to get things done faster. My partner and I selected certain designs with certain shapes for specific…
Theory When preforming an experiment using the scientific process one of the most essential components is comparing theory to actual measurements. This relies on the accuracy and uncertainty of the measurement itself. If an actual measurement proves the theory wrong it you must know the uncertainty so you can try to figure out where the error took place. Uncertainty can arise from a few different areas; they are statistical variation, measurement precision, or systematic error. Systematic…
Report: Molar Volume of a Gas at STP Abstract: The purpose of this experiment is to find out how to experimentally determine what the volume of a mole of H₂(g) is at STP by using gas laws. The hypothesis for the experiment is that if H₂(g) is produced at RT and STP, Avogadro’s law can be used to experimentally determine the amount of H₂(g) because equal gases at the same pressure and temperature have the same amount of particles. In order to find the molar volume, hydrogen gas was…
The lab conducted was to investigate the density of not only copper but also diet and non-diet soda. Techniques used in the experiment included water-displacement, measuring copper’s dimensions, and using volumetric pipettes to measure out specific soda volumes. Beginning Question(s): How does the use of two experimental methods, improve the chances of calculating the density of copper? How does the density of non-diet soda compare to that of diet soda measured at different volumes? Safety…
20, 2016 Erin Whitehouse The first part of the experiment consisted of finding the accuracy and precision of three different measuring devices, a 50mL beaker, a 25mL graduated cylinder and a 25mL pipette. The mean volumes and uncertainties were found to be 22.5mL 1.9, 23.72 .25, and 24.89 .43, respectfully. The 25mL pipette was found to be the most accurate out of the three. The density of water was found to be 0.9979 g/cc with a percent error of .08, while the known density of water being…
Objective- Our goal for this lab was to calculate the Density of a substance. We needed to make sure we had the materials to find mass and volume and then use a formula to calculate density. Introduction- The main principle of this experiment was to figure out the Density of certain objectives given to us in the lab. We had to know the the formula D-M/V in order to find the density of that object.We also needed to know the density of water(1.0 g/l) in order to predict if something would float…
FedEx has experienced steady growth in holiday volumes since 2007. They forecasted another record holiday in 2015. FedEx expected they would move more than 290 million packages during Black Friday and Christmas Eve, which resulted in a 9 percent increase in overall year-over-year seasonal volume. FedEx also forecasted the busiest day in company history was December 15, 2015 with a forecasted 22.6 million shipments moving around the world. Their peak projections included FedEx earnings…
density calculation would be the most accurate. The second question asked if the sugar in the soda had an effect on its density. The third question stated what affect the varying size and shape of the copper pieces had on their density. These questions were explored in the experiment and some interesting conclusions were made at the end. In the first half of the experiment, the density of copper is calculated using two different methods of measurement. The objective of the experiment was to…
Aim The aim of this practical is to measure the effect of volume, density and temperature. It is also help to be familiar with variety of common laboratory technique.

Label and weight accurately, to 4 decimal places. Collect…
approximately thirty thousand deliverables. Fulfillment Operation would extensively use planning, organization, leading and controlling in its operations. Much of the fulfillment would be processed through our automated channel if there were no issues involved. When we would get these exceptions, we would push these requests to our manual workflow. Our associates would quality check the work to verify all documents were generated and we would prevent privacy breaches. The department operated…
