Joule Thompson effect - Lab Report Example Credible sources were used to provide the needed literature review that would help in producing relevant information on the discoveries that preceded the Joule-Thomson experiment. Two equations and a diagram were given to form the basis of the work. A description of what the experiment was designed to test vis-a-vis the outcome that was expected It also became important to vividly describe what the Joule-Thomson experiment was designed to test and the outcome that was expected from this experiment. This would help us to know what Joule and Thomson sought to achieve in their experiment. From this expected outcome, it would be possible to deduce the result of the Joule-Thomson experiment. A detailed explanation of the experimental setup and procedure The experimental set-up and the procedure of the Joule-Thomson experiment were well detailed in this section. This helped to have a full understanding of the subject matter. The apparatus that was used in the experiment were highlighted an d the procedure for a typical Joule-Thomson experiment was properly elaborated. A diagram to show what a typical Joule-Thomson experiment should look like was also presented. The experimental setup and procedure was given in a step by step manner as this was done in order to ease the comprehension of the Joule-Thomson experiment. ... Hence, that was the notion behind this section. The criticisms that greeted the Joule-Thomson experiment and the impact of the experiment in the scientific advancement were briefly analyzed. The Sources for the work The report was processed in the MLA format. Three websites were used for this paper for ease of accessibility and one text book to balance the credibility of the work. The sources that were consulted for this paper are given below: Physical Chemistry by Joseph Noggle, http://home.sou.edu/~chapman/ch444/JOULET.HTM, www.pdfcari.com/THE-JOULE-THOMSON- EXPERIMENT.html & www.chem.arizona.edu/~salzmanr/480a/480ants/jadjte/jadjte.html Name of Student Name of Lecturer Course 27 June 2011 Joule Thompson effect The historical context of experiment It was based on a basic assumption of the Kinetic Theory of Gases that there is no significant force of attraction between molecules of an ideal gas that Gay-Lussac and J.P. Joule presented the relevant discoveries that preceded the Joule -Thompson effect. Gay-Lussac and J.P. Joule discovered that gas molecules attract one another (Noggle 104). They believed that the fact that gaseous molecules attract one another means that there is a force of attraction between them that is too significant to be neglected. They reiterated working on the dependence of energy of gases on pressure and as a result they investigated the dependence of energy of gases on pressure (Noggle 104). The apparatus that was used by Gay-Lussac and J.P. Joule are as follows: Copper bulbs A and B, Valve V and Water-bath and a sensitive thermometer. Air was pumped into Bulb A under pressure and this was secluded from the Copper Bulb
