Volume

A Helmholtz resonator is a rigid container which has an opening to the air surrounding it. A common example of a Helmholtz resonator is a bottle because it has a set volume as well as having an opening which is open to the surrounding air. By considering the Helmholtz resonator as having a neck, such as the neck of a wine bottle, the dynamics of the system may be described. When energy is introduced near the opening of the bottle, for example blowing across it, some of the energy will vibrate…

Introduction The Last Lion: Winston Spencer Churchill is a trilogy of books written by William Manchester, a renowned biographer and historian. They first volume was Visions of Glory published in 1983, the second volume was Alone published in 1988 and the third volume was Defender of the Realm, co-authored with Paul Reid and published posthumous. The three books feature Winston Churchill, the famous British Prime Minister who led the Empire into the Second World War. Each of the three covers of…

The objectives of this experiment were to determine how temperature affects the volume of a gas and to conclude the best way to ship a gas. This information was highly beneficial to a company involving the production and transportation of propane. The experiment assisted in finding the best method to ship a gas in order to maximize profits for the company and decrease the cost of transportation. In order to be successful in the experiment, there were two principles that needed to be discussed…

allows an organization to prediction of cost and profit among different volumes and is used in setting up a flexible budget. This method helps in controlling, formulating policies and being able to designated cost depending on their level of output. Some of the limitation of using this method is that variable are not constant, fixed costs stabilize at higher volumes, discounts may be applied during times of higher volumes (Yash, 2014). Understanding the benefits and limitations that CVP…

Results: Starting volume of styrene: 1.7 mL Theoretical yield of 2-phenylethanol: 1.796 mL Mass of 2-phenylethanol collected after rotovap: 1.408g Volume of 2-phenylethanol collected: mass collected/density Volume collected: 1.408g/(1.02g/mL)= 1.38 mL Percent yield= (volume product/volume starting styrene) *100 Percent yield= (1.38 mL/ 1.7 mL)*100= 81.2% Peaks on the product IR graph: Between 3300-3400…

of the the tidal volume (TV), the inspiratory reserve volume (IRV), the expiratory reserve volume (ERV), and the vital capacity. Vital capacity is dependent on age and gender (Harris-Haller, 237). The lungs are fully developed by the age of twenty (“Lung Capacity and Aging”, 2018). By setting up the spirometer and collecting the tidal volume, the inspiratory reserve volume, and the expiratory volume, the vital capacity of the human lungs can be calculated by adding the three volumes together.…

The peak in the September was followed by lower price movements that corresponded with volume spikes, thus implying that the downtrend was going to continuously. 3.5.5 Moving average convergence divergence (MACD): Common, the “MACD” is a trend following, momentum indicator that shows the relationship between 2 moving averages of stock prices…

Physical properties do not change the chemical composition of the substance. Physical properties include; density, boiling point, and solubility, etc. The density of a substance is the ratio of the mass of the substance to its volume. Density (ρ) = mass (M) / volume (V). The boiling point of a substance is the temperature at which the liquid form of the substance starts to change to its vapor form. Solubility is defined the degree at which a substance (solute) dissolves in another substance…

Ativan. viii. Sodium Chloride (Hypertonic Saline 3% inhalation solution) 4 ml, Route: nebulizer solution via in- line SVN (small volume nebulizer) inhalation, every six hours (Q6H)  It was prescribed to the patient to thin airway secretions in the lung so it will be easier to remove via suctioning. ix. Tobramycin 80 mg, Route: nebulizer solution via in- line SVN (small volume nebulizer) inhalation, every twelve hours…

The unknown base concentration of a sodium hydroxide solution can be determined by titration potassium hydrogen phthalate (KHP) with an unknown concentration of sodium hydroxide NaOH. The average molarity of NaOH determine by the moles and volume of the KHP and NaOH. (Eq 1). KHC8H4O4(aq) + NaOH(aq) = H2O(l) + NaKC8H4O4(aq) (Eq 1) The unknown concentration of white vinegar can be determined by the white vinegar with the known concentration of…
