Experiment 5 Polytropic Expansion of Air Object The object of this experiment is to find the relation between pressure and volume for the expansion of air in a pressure vessel – this expansion is a thermodynamic process. Introduction The expansion or compression of a gas can be described by the polytropic relation ‚ where p is pressure‚ v is specific volume‚ c is a constant and the exponent n depends on the thermodynamic process. In our experiment compressed air in a steel

Courtney Ulrick Lab Experiment #4 Properties of Gases Purpose: The purpose of this experiment was to understand the gases; Hydrogen‚ Oxygen‚ and Carbon Dioxide. The experiment helped me understand the properties of these gases‚ specifically their physical and chemical properties. Data: Gas | Flame Reaction | Glowing Splint | Limewater Reaction | Bromothymol Blue Reaction | Hydrogen | Loud Pop | | | | Oxygen | | Glowing Brighter | | | Hydrogen & Oxygen | Loud Pop‚ extinguished

The knowledge of the natural moisture content is essential in all studies of soil mechanics. To sight a few‚ natural moisture content is used in determining the bearing capacity and settlement. The natural moisture content will

social science “Milgram Experiments” were used to discover of the people would willingly hurt another person because someone of authority told them to do it but the participants were told that the purpose of the experiment was to study memory with punishments. Ethic and moral dilemmas appeared during the experiment that criticized the research and its methods because of its deception and stress that it puts on the volunteers. There are multiple reasons why the experiment could be used to show the

TITLE : Tensile Test ABSTRACT The tensile test experiment being done purposely to determine the deformation of our specimen which is low carbon steel or also called as mild steel‚ and it also to identify the fracture characteristic of the specimen based on the result that we got through the experiment. Based on the data presence from this experiment ‚we used it to calculate the stress and strain using a theoretical formula. Through all the calculation that we got‚ we construct a table and

Hypothesis If we test the amount of electrolytes in an energy drink and orange juice‚ then orange juice will have more electrolytes than an energy drink. Variables Independent Variable- the two different drinks‚ orange juice and an energy drink Dependent Variable- the amount of electrolytes in each to determine whether or not one has more than another Controlled Variable- same multimeter‚ same brand and type of alligator clips leads‚ same gauge‚ length‚ and brand of copper wiring‚ same brand

Abstract The aim of my research was to study automatic processes by replicating the previously carried out Stroop effect. The participants‚ 20 Richmond College students (10 boys and 10 girls) chosen by an opportunistic sample were taken into a quiet room separately‚ were presented with 6 lists of words‚ out of which 3 were congruent and the other 3 incongruent and the time taken for each participant to name the colour that the words were written in was measured and recorded. From

the findings of a study conducted in 1951. Solomon Asch (1907 1996) originally conducted this experiment to explain conformity to majority-established norms (Moghaddam‚ 1998). The subjects involved in the study were brought into a room with seven other students (who were all working for Asch and were instructed on what to do) and seated second-to-last around a table. The subjects were told that the experiment was concerned with accuracy and visual perception‚ and that their task was to choose which
