Atmospheric reentry

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…

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).…

Exercise 1 The abundance of nitrogen in the standard dry atmospheric composition is 781,000ppmv. The mass mixing ratio is the volume mixing ratio multiplied by the molecular mass of nitrogen all divided by the molecular mass of air. As the molecular mass of air, 28.8g, is higher than the molecular mass of nitrogen, 28g, the mass mixing ratio would be lower than the volume mixing ratio. a) m=F/a m=101300/9.8=10,336 An estimate of the total mass of a column of the atmosphere with a base…

It is easy for us to neglect the immediate and colossus problems plaguing our world, because the biggest problems, the ones that affect not only our future generations here in America, but the future generations across the globe, seem like they are flames, too bright to look at. We know it is there, yet instead of trying to put out the fires, we turn away, hoping someone else will eventually do it for us. One of the biggest, if not the biggest, flame destroying our world is the unbelievably high…

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…

Altitude sickness, is divided into 3 different levels of intensity, Acute Mountain Sickness (AMS), High Altitude Cerebral Edema (HACE), and High Altitude Pulmonary Edema (HAPE). These illnesses occur when someone is exposed to levels of higher elevation, reduced oxygen levels and lowered air pressure. Altitude sickness causes the veins and capillaries to expand in order to take in more oxygen. Some scientists also believe that it can cause the brain to slightly swell. Altitude sickness can…

Our product Evapor-Paint is a problem solving paint for any home renter, teacher, or college student. We have designed a product that allows you to paint whatever you wish, but not having to commit to it. With Evapor-Paint, you can remove your creation with water and will be gone within a day. Most people who are in a temporary living space are not able to express themselves in their homes, our product gives them that freedom. The positive fact about Evapor-Paint is that their is not a huge…

The atmosphere presses down on the earth an average of about 14.7 pounds of weight on every square inch it touches. Most people’s shoulders have an area of 12 square inches. So overall, the weight pressing on your shoulders is equaled out to be 176 pounds! This is called atmosphere pressure. Now it certainly doesn’t feel like there is 176 pounds pressing on me all day long, but there is an equal pressure pushing on me from all sides, including from within. In this experiment, we will…

Literary Analysis: The Great Gatsby Weather can alter mood not just within ourselves, but it can be equally atmospheric in literature as well. Although it is not a dominant symbol, the weather in The Great Gatsby is nonetheless an important emblem that metaphorically reveals the character’s emotions while establishing the narrative tone. Fitzgerald uses the weather to establish the moods for every scene, and each change in mood serves as an indication of each character’s state of being. In doing…

two nations could work together in space (Aronson 63). However, in the end, the SALT agreement had little impact on Soviet arms relations because it solely put limits on offensive nuclear systems, but did not limit multiple independently targetable reentry vehicles, and, in essence, allowed the arms race to continue (Drew 85).…
