Behavior of Gases Essay Example for Free

Behavior of Gases Essay Introduction: In this experiment, the problem trying to be solved is what gas laws are being used when the pressure, temperature, and volume are being measured. The three gas laws are Boyle’s Law, Charle’s Law, and Gay-Lussac’s Law. The Boyle’s Law is when volume and pressure are being compared. Pressure and volume are inversely proportional, because when pressure goes up, volume goes down. The Charle’s Law is when volume and temperature are compared. Volume and temperature are also inversely proportional as well. Lastly, Gay-Lussac’s Law is when pressure and temperature are compared. Pressure and temperature are directly proportional; therefore when pressure goes up, temperature also goes up. The formulas are as follows: Boyle’s Law: P2 P1 = P2 V2 Charle’s Law: V1/T1 = V2/T2 Gay-Lussac’s Law: P1/T1 = P2/T2 Hypothesis: If volume, temperature, and pressure are measured, they will follow the laws and fit under Boyle’s, Charle’s, or Gay-Lussac’s law. Expected Results: It should be expected that when volume and pressure are measured, pressure will go up and volume will go down. When volume and temperature are compared, volume will go up and temperature will go down. Lastly, when pressure andtemperature are measured, pressure will go up as temperature goes up. Experimental Procedure: Part I Connect a 20mL syringe to a LabQuest Select: File New Then, Mode: Change to Events with Entry Next, Enter Name as Volume Enter Units as mL Select OK Start at 10mL on the syringe and wait for the reading to Select Keep Keep at least 6 data points (any of your choice) Only pull the syringe out (making the mL readings higher each time) Stop the Data Collection and view the graph and points Record Part II Place an Erlenmeyer flask in a beaker big enough to fit the flask Connect a temperature apparatus to the Lab Quest and place probe in beaker Then connect the pressure tube to the Lab Quest in channel 2 and connect the other end of the tube with the rubber stopper to the Erlenmeyer flask Select: File New Then Mode: Change to Selected Events Exit In sensors menu, change units to Kelvin Tap graph X-axis: chose temperature Place faucet, room temperature water in the beaker Select Keep Place ice in the beaker Select Keep Place room temperature water in the beaker again and place on a hot plate Wait for the water to boil Place temperature probe and Erlenmeyer flask back in beaker Select Keep Record result from graph and chart Results: VOLUME (mL) PRESSURE 10 103. 27 12 87. 6 14 76. 14 16 67. 5 18 60. 96 20 55. 15 This data and chart is comparing volume and pressure. The graph represents the Boyle’s Law because as the pressure is going up the volume is going down. TYPE OF WATER TEMPERATURE (K) PRESSURE Normal 102. 8 295 Ice 98. 29 275. 4 Boiling 122. 31 357. 4 This data and chart is comparing temperature and pressure. The graph represents Gay-Lussac’s Law because as temperature goes up, pressure goes up as well. Discussion: This experiment went extremely smooth. The data was easy to collect as long as you kept the Lab Quest and tools stable to ensure for accurate readings for temperature, pressure, and volume. The graphs and data easily coincided correctly with the theories of the gas laws, as was shown accessibly once the graphs were made. Although the data coincided with the theories correctly, the temperature readings for freezing and boiling may have not been completely accurate because the temperatures of the water was not measured accurately for correct boiling and freezing temperatures, but recorded solely for the theories and to prove them. Overall, the experiment held up well and the hypothesis and theories were proven to be correct. Behavior of Gases. (2018, Oct 25).

Clinical Care Classification System Essay Example | Topics and Well Written Essays - 2000 words

Clinical Care Classification System - Essay Example Through care, management programs are new systems that respond to the problems associated with the health sector. The mechanisms of the IMA and the Insight Plus have been implemented towards the establishment of better medical aid. Some failure and successes are evident through the undertakings. Medical informatics requires relevant vocabularies in order to support the best application within the existent medical standards. The medical informatics tends to describe the required standards to the international users and other personalities within the fields that utilize similar standards. The adoption process have been relatively slow given that for the past years since implementation, the system development has encountered difficulties attempting to meet the international scale needs. According to Cimino (1998), the looming question over the terms added to the vocabulary has been-‘why don’t it have what I want it to say?’ This correspondingly implies that the addition of more terms that meets the requirement of most people must be implemented for the system to work efficiently. Through implementing the list within the desiderata, there are possibilities of establishing controlled vocabularies sharable and reusable. Several aspects tend to hinder the task of listing the desiderata for the controlled vocabularies. Firstly, the desired characteristics of the vocabulary must be multipurpose in nature, and there are multiple intended purposes. The desired characteristics targeted by the listing range from: capturing clinical findings, the natural language processing, medical indexing records, indexing medical literature and representing medical knowledge (Cimmo, 1998). Aside from the above-mentioned problems in summarizing desiderata, differentiating opinions and putting them together is a major problem relative to the listings. According to Cimmo in his article ‘Desiderata for Controlled Medical Vocabularies in the twenty-First

Constrained Women Essay Example | Topics and Well Written Essays - 1000 words

Constrained Women - Essay Example Short stories can often focus a reader’s attention on various elements of our lives that frequently pass by under our radar because they are now so deeply ingrained in our society’s norms. Such concepts in our life would include the inherent male-dominant beliefs of old in which the woman’s space is considered to be only within the home. On a social level, the woman’s place remains below men even in modern times and is usually placed only slightly above children in matters of importance. While these are ideologies that have, in the past 100 years, been increasingly challenged, particularly by women who have continued to demonstrate their ability to keep up with men, it remains the case that women continue to struggle, not simply on the social level, but on the personal level as well. This personal battle in the example of female subservience requires women to begin questioning the values learned in their youth to consider something both thrilling and frigh tening – the idea that they may be capable of making their own decisions in life without the leadership or approval of men. For many women, the concept alone would be the most they would achieve, especially in earlier time periods. The female characters found in William Faulkner’s short story â€Å"A Rose for Emily† and Shirley Jackson’s short story â€Å"The Lottery† live within this oppressive ideology of the subservient woman both socially and internally, but also exhibit a yearning to escape the ties that bind them.
