1. Compare two poems that were not present as pairs on our syllabus but were assigned on different days. How do these poems speak to one another? Two poems that were not present as pairs in our syllabus that have some things in common would be, Fond Memory and Marks. In Marks, it talks about a mom being graded by her family on things she does. In the poem, she writes, “My husband gives me an A, for last night's supper, an incomplete for my ironing, a B-plus in bed.” This is a common…

Atmospheric Global Circulation is the movement of air caused by solar energy and the interaction of warm and cold air - this convergence forms cells or belts over the Earth’s surface. George Hadley (1685–1768) a British physicist and meteorologist, who first described this theory in 1753, did so using what is known as the Single-Cell Atmospheric Global Circulation Model or Hadley Cell (The Editors of Encyclopædia Britannica, 2007). Hadley’s Single-Cell theory failed to consider the Coriolis…

One of the main abiotic factors influencing the distribution of biomes is global atmospheric circulation. Global atmospheric circulation is the mass movement of air around earth caused by thermal energy. This mass movement of air causes three distinct atmospheric circulation cells to form, these are the Hadley Cell, Ferrel Cell and Polar Cell. Between these three cells is a dynamic area called the Intertropical Convergence Zone. Persson (2006) tells us that the Hadley Cell is caused by solar…

the character’s situation and decide what we would do, learning more about ourselves. The message of this book is that peer pressure can lead to a path of destruction from the choices that you made, which will change your life forever making you someone you're not, close to a point of no return. Peer pressure is relevant because we see kids in society influenced by peer pressure who end up making the wrong decisions that go against morals, values,…

Introduction Vapor pressure is the pressure of a vapor (gas) at equilibrium; equilibrium occurs when there is no net change between the amount of liquid and the amount of vapor because they balance each other. When the temperature of water becomes extremely low, as it does in this experiment, the rate of vaporization does not matter. The objective of this experiment is to determine the experimental heat of vaporization and compare it to the accepted heat of vaporization of water (40.7 kj/mol).…

experiments on pressure systems conducted, the Marcet boiler and Boyle’s law. The aim of this lab is to investigate in pressure-temperature relationship, Boyle’s law, as well as steam quality. The results of this experiment support both relationship, as well as successfully providing a value for steam quality. For the Marcet boiler experiment, it was found that the higher the system pressure, the higher the saturated temperature. For the Boyle’s law experiment, it was found that pressure is…

attention of millions in the United States. Although teams compete in the most inclement frigid weather, it is a sport that has played an intricate role in uniting families as well as communities in friendly banter, while taking one’s mind off the pressures that may engulf them on a daily basis. And even though this holds true, occasionally, during the season one will experience an upset or a scandal that will rock the nation. The world has bore witness to these types of upsets where the…

Pressure vs. Volume and Boyle’s Law Pre-Lab Questions According to our modern understanding of the gas laws, there are four measurable properties (variables) of a gas. These variables are P (pressure), V (volume), T (temperature), and n (number of moles). In Boyle’s experiment, which two variables were held constant? Both the temperature (T) and the number of moles of gas (n) were held constant in Boyle’s experiment. Fill in the blanks to summarize the relationship among the gas properties in…

3.3.2. Initial and Boundary Conditions. The pipe is subject to atmospheric pressure Po at time zero this represented initial condition . Boundary condition represented as at the pipe inlet profiles, uniform pressure Pinlet and its value change with concentration of nanofluid [φ%] and inlet temperature T0 = 60 ºC can be measured for all experimental . On the pipe wall, the pressure was atmospheric pressure Po . Moreover, flow and thermal fields are assumed symmetrical with respect to…

stopper is inserted into a flask some air is forced out of the flask, and the stopper seals the flask so the air cannot get back in. This creates an area of low pressure within the flask. When the stopper is quickly pulled out of the flask, the air rushes back into the flask because the pressure of the atmosphere is higher than the pressure inside the flask. If the stopper is pulled out with sufficient force and swiftness, a “popping” sound is produced that corresponds to the resonant frequency…
