Lab two explored varies ways to find the density of objects. This lab used displacement , measurement, and the density formula to make observation and collect data about the balloon filled with sublimed dry ice, various water samples, and a golf ball. The ultimate goals of this experiment were to collect the most precise measurements of displacement of the balloon in the tap water, the weight of the three water samples versus the original cylinder, and diameter of the golf ball in order to use…
to determine the density of an unknown liquid. Additionally, the opposite process was used to determine the calibration of a piece of glassware using a known density. In the first activity, “Density of Liquids”, the identity of a liquid was determined by calculating its density (g/mL). First the mass (g) of a specific volume (mL) of water and the unknown liquid was found. Their densities (g/mL) were then calculated by dividing the mass (g) by the density), the calculated density was then…
Experiment 2: The Size of Molecules & Avogadro’s Number Name: Julia Bland Lab Section: Tuesday A.M. (11:30) TA’s Name: Yuogi Date: October 15th Course: CHEM 1001 Abstract: Avogadro’s number is one of the vital constants in the chemistry world, used in a multitude of experimental and theoretical calculations. This lab endeavours to experimentally measure Avogadro’s number by adding drops of stearic acid into a known area of distilled water, and using this data, calculate the molecules in…
Material bulk engineering properties such as angle of repose, bulk density, grain to grain angle of internal friction and cohesion can be easily be measured from laboratory tests and related to grain-machine interaction systems responses where the micro parameters in DEM models are developed using particle-particle friction, particle-geometry friction and the particle density to simulate material behavior (Asaf et al., 2007). The particle size and shape distribution are…
Introduction: Microclimate is the difference in climate that occurs on a very small scale. Microclimate can be created because of altitude, aspect, vegetation, color of the ground, and boulders and burrows. Aspect is created in the presence of topographic features like hills, mountains, and valleys. In the Northern Hemisphere, the north-facing slopes are cooler because they receive less sun than the south-facing slopes. Since they receive less sun, they are also moister due to decreased…
On the topic of Jacob’s ideas to discourage criminal behavior, she is an open critic of the common theory of improving cities’ vibrancies by making room for more green space before considering whether the new parks would be properly integrated . If a park is located in “a low-traffic area such as the residential edge of a neighborhood, ” misallocated green space can become “havens for transient populations or criminal activity ,” and become the type of place where teenagers go to abuse drugs or…
Introduction: This report will be talking about osteoarthritis in the Waitemata district. It includes the epidemiology of osteoarthritis (OA) and its biological changes, the health needs associated with osteoarthritis in the Waitemata district health board population, and a policy and service that is involved in reducing the health need. OA is one of the most common types of arthritis and is a degenerative joint disease. It is a leading cause of pain and disability problems for middle to elderly…
distinctions may be realized in terms of city demographics, city administration structures, geographical locales, infrastructure and public facility configuration, and economic systems, among other city aspects and factors. Employing data collection and high level thinking skills, research is carried out to compare and contrast two Asian megacities. In particular, this city report presents the differences and similarities between Hong Kong and Tokyo with respect to cultural orientations,…
important cells. Bone health, commonly measured by bone density, is often overlooked, with other health issues such as obesity, cancer, and heart disease getting much of the…
The correct answer is C Osteitis Deformans (also known as Paget’s disease). Paget's is caused by the excessive breakdown and formation of bone, followed by disorganized bone remodeling. This causes affected bone to weaken, resulting in pain, misshapen bones, fractures and arthritis in the joints near the affected bones. An elevated level of alkaline phosphatase in the blood in combination with normal calcium, phosphate, and aminotransferase levels in an elderly patient are suggestive of Paget's…
