Introduction The purpose of the lab was to see the effects of heart rate and blood pressure when 3 male and 3 female students exercised compared to when they were at rest. My hypothesis is that the data from the exercise part of the experiment will cause both the heart rate and blood pressure (systolic and diastolic) to increase more than the resting state. Methods Resting heart rate was recorded in the begging of class. Then the class was divided into groups and from each group, there was a…

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…
liquid and its velocity. The capillary pressure at porous media is defined as the difference between pressure in the liquid and vapor phase. Mass conservation for liquid phase is as follow: (18) (∂(εsρ_l))/∂t+∇.(ρ_l u ⃗_l )=S_(g-l) Darcy law can be used for liquid momentum equation in porous media; therefore, momentum equation is reduced and can be expressed by: (19) u ⃗_l=-K_l/μ_l ∇p_l Also, the liquid pressure can be extracted from definition of capillary pressure. (20) p_c=p_g-p_l=f(s)…
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…
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…
