Data that supports this is that canister number one had the least amount of sand and a density of 0.40g/mL3.This canister was the least dense of the three canisters. This is why it floated on the surface of the water. Opposed to canisters numbers two with more sand than canister number two and canister number three had the most sand .Water’s density is 1 g/mL3 . The reason canister one floated was because it’s density was less that water. Based on the data collected it infers that the more sand…

Does a Measurement Result in a True Value? Limitations of Measurements Elizabeth Lechtholz-Zey & Marisa Loredo 10/5/15 CHEM 101-08 Purpose To determine the differences in precision and accuracy in weighing 10 mL of water using a 50 mL beaker, a 10 mL graduated cylinder, and a 50 mL buret. Data Temperature of water: 23.0ºC 100 mL beaker weight: 50.557 g # of additions of water to the 100 mL beaker * 50 mL beaker (±5 mL) * 10 mL graduated cylinder (±0.05 mL) * 50 mL buret…

Density of Sand The objective of this lab is to use knowledge from previous labs, like the density of water and solids lab, and apply it to find the density of sand. First you must weigh your graduated cylinder, and record the weight, then pour in whatever amount of sand you choose. You then must weigh that to find the mass, and subtract whatever you got by the mass of the graduated cylinder. After that you pour in some water, and find the difference of how much the water went up and, what the…

When comparing the results of each subject in a group, they show that the control, or the subject that had no fluid intake during the experiment had very less or no fluid output in every 20 minutes unlike the subject that had about 5ml/kg-1 of water intake. The results also show that caffeine and exercise affect the amount of urine produced in different ways: the caffeine seems to increase the total amount of urine that is produced while exercise decreases the total amount of urine produced.…

Introduction and Theory: 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…

Introduction: Water quality is the scientific measurement describing the cleanliness of water and/or the condition of the water being studied. Factors that used to describe water quality are pH, Dissolved Oxygen, Temperature, Turbidity, Nitrogen, Biological Oxygen Demand (BOD), Fecal Coliform, Phosphate, and Total Solids. Water quality is important to know because water is a necessary part of life, and people need to know how clean the water they’re using is. Water quality is important for…

water into the beaker, and then reweighing the beaker. Next, the weight of water was calculated by subtracting the weight of the empty beaker from the weight of the beaker containing water. These values were then converted to water volume using the density of water at a temperature of 19.5 °C; 0.998 g/ml. The weight of water measurements, 9.82 g, 9.90 g, and 9.94 g, were converted to water volume by dividing by 0.998 g/ml as shown below. Volume = (9.82 g) / (0.998 g/mL) = 9.84 mL Volume =…

Introduction A vessel floating in water reacts to its environment with motion. It has six degrees of freedom, three translational and three rotational. When the floating vessel is attached to appendages, which in this case is mooring lines and risers, these attached slender structures also have effect on how the vessel reacts to the environmental loads. This study is to understand how these effects are analysed. In this chapter, the solution of the uncoupled and coupled analysis is going to be…

Injection Machine 4.6.1 Calculation of the Injection Volume Figure 4-8 shows the volume of plastic parts by Solidworks modeling. Figure 4-8 Volume of the Stress Cone Plastic parts volume: Vplastic = 4.198 × 10-5 m3 = 41.98 cm3 Plastic parts density: ρ = 1.2 g/cm3 Plastic parts quality: mplastic = ρVplastic = 1.2 × 41.98 = 50.376 g 4.6.2 Preliminary Estimation of the Gating System Although the gating system of condensate cannot determine the exact value prior to design, it can be…

Our experiment was centered on taking four testing groups and setting a baseline level of dehydration across all four groups. From there each group would be assigned water, coke, Gatorade or remain dehydrated. The test subjects would then consume their assigned drinks based on their body weight. Urine would then be collected at thirty-minute time intervals to measure urine changes. The goal of our experiment was to determine the influence of fluids being introduced into the body of various…
