Volume

Famous Stock Analyst Marc Chaikin created Chaikin Money Flow which measures the amount of Money Flow Volume over a specific period. The Chaikin Money Flow oscillator is calculated from the daily readings of the Accumulation/Distribution Line. Chaikin believed that buying and selling pressures could be determined by where a period closes in relation to its high/low range. If the period closes in the upper half of the range, then buying pressure is higher and if the period closes in the lower…

oxygen volume amount would have to be increased, which is achieved by taking in or inspiring more often. This can be shown by looking at the result above. The value for breathing rate was initially 15 breaths per minute, and this increased by 25, to 40 breaths per minute after the exercise was completed. Peak flow It measures the fastest rate…

determine the number of moles of nitrogen, that will lead to determine the value of R by measuring P, V, and T. Theory/Principles A physical law such as Boyle’s law states that P, the exerted fixed mass of gas at a constant temperature and V, the volume have a relationship. Their kind of relationship is V=f(P) relationship and it is believed that PV go together to remain constant. A water manometer is an instrument used to measure pressure. The model of kinetic theory of gases helps elaborate…

Analysis of aspirin tablets Purpose: Determine the percentage of 2-ethanoylhydroxybenzoic acid in aspirin tablets. Introduction (including background information) : Before creating Aspirin, “sail alba” was used. In 1860’s, chemists discovered that Salicylic acid (2-hydroxybenzoic acid, C7H6O3 ) is the active acid in sail alba. Salicylic acid is relatively strong though. It can irritate and damage the stomach membranes and mouth. In 1889, ethanoate ester of salicylic acid was introduced by the…

NTRODUCTION In this experiment the validity of Gas Laws were observed and the relationship of two variables, temperature and volume, against pressure was tested. Gas Laws are encompassed by the Ideal Gas Law in which PV=nRT observes the general behavior of a gas under ideal conditions in terms of pressure(P), volume(V), moles of gas(n), gas constant(R), and temperature(T). The Ideal Gas Law is a combination of Boyle 's Law, Charles ' Law and Avogadro 's Law and was first introduced in 1834 by…

Introduction Density measures the volume that a given amount of mass takes up. Usually, density has grams per unit volume as a unit. To find the density of an object, the object has to be measured and its mass has to be divided by its volume. Often times, density is used to identify substances, since different elements have specific densities. This experiment is made up of two sections; the first section measures the density of water and the density of an unknown substance. If the procedure is…

Article Summary In the article by Ezzati, Zimmerman, Mindy, Katz Sundermann, Smith, Lipton and Lipton (2014), the goal was to look at the relationship between pain and hippocampal volumes in older cognitively intact adults. Specifically, this study was looking at differences in volume in subparts of the hippocampus as related to pain. This study looked at 86 adults over the age of 70 with a mean age of 80.2 years. Additionally, 53.8% were women, and 54.7% were white, and the sample had a mean…

we were able measured the tidal volume. This allows us to measure if working out changes the amount of air being taken in by the lungs. The dependent variable is the tidal volume, and the independent variable is the amount of jumping jacks being completed by the subject. There were three levels of treatment: 30, 40, and 50 jumping jacks. To start out each trial we measured the subject’s tidal volume. As soon as the jumping jacks were done, the tidal volume was measured with the spirometer.…

strengths are shown in table 2. It is seen that the tensile strength of the jute/epoxy composite increases with increase in fiber volume fraction up to 10 vol. % and then decreases at 12.5 vol. %. While Coir/epoxy composites tensile strength continuously decreases with increases fiber percentage. Tensile strength of coir/epoxy composite at 8.3, 10 and 12.5 % volume fraction were 28.07, 27.72 and 26.28 MPA respectively. The highest tensile strength was found in 10…

Solids are anything with definite volume/definite shape. Liquids are substances with definite volume and indefinite shape. Gases are substances with indefinite volume and indefinite shape. Physical properties are things that can be measured or observed without changing the identity of a substance. Physical changes are changes of matter without changing…
