It begins on a 6 acre piece of land as an oil rig, with other large machinery and generators. The process includes injecting a mixture of water, sand, and chemicals at a high pressure to break shale rocks and release the natural gas inside. Amongst many shale formations in the U.S., the shale area that spreads from eastern Ohio to western Pennsylvania is called Marcellus. The shale rocks are nearly 5,000 to 8,000 feet underground…
barrier from the decaying world below. Regardless of their class, individuals underwent this transformation for a chance at a prosperous life. However, that was 100 years ago and although, the higher altitude offered protection, it provided excess water vapor that was accumulating in people’s lungs and, drowning them. Cirrus looked out over…
them the reason she took her own life. Mirikatini writes this note from the young Asian-American’s pressure-filled mind who has battled with the feeling of being “not good enough” for too long. This poem is filled with many comparisons and analogies that descriptively illustrate what the girl that Mirikitani writes about was thinking and feeling. The suicide note displays the overwhelming pressure that young adults feel from their families and friends, how prevalent suicide is in today’s society…
volume of a mole of H_(2(g)) is 22.4 L, it supports Avogadro’s law that one mole of an ideal gas occupies 22.4 L at STP. At the same time, it indicates that a direct relationship exists between volume and the number of moles of gas as temperature and pressure stays constant. One real world application of the importance of this problem is demonstrated when a helium balloon is lighter than an identical balloon filled with air…
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…
results. The first experiment studied the relationship between volume and pressure, while keeping the amount of the gas sample and temperature constant. Table 1 shows the atmospheric pressure recorded during the experiment. Atmospheric Pressure (mm Hg) 644.0 mm Hg Table 1. Atmospheric pressure was recorded using barometer in lab next door. This atmospheric pressure is of the lab next door, and is not the atmospheric pressure in which the experiment took place. Possible errors from this…

October 2016 College Pressures College is a time of anxiety and panic for many students all over the world. In the piece, “College Pressures” by William Zinsser, there is talk about the pressures of college and advises how to handle these moments of breakdown. Through the late nights and tears shed, you have feelings of high doubt and stress. Zinsser points out the four main pressures of college as being “economic pressure, parental pressure, peer pressure and self-induced pressure” (275). The…
Ultrasonic interferometer Working principle An ultrasonic interferometer is a simple and direct device to determine the ultrasonic velocity in liquids with a high degree of accuracy. An ultrasonic interferometer is used to determine the accurate ultrasonic velocity in liquids. The principle used in the measurement of velocity is based on the accurate determination of the wavelength in the medium. The principle of ultrasonic interferometer for the measurement of velocity is determination of 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…
