Boyle’s Law Experiment Aim To show that Pressure is proportional to the inverse to volume Method A gas syringe was attached to a pressure sensor. The pressure sensor was calibrated‚ assuming the atmospheric pressure at the time of the experiment was 100kPa. Differing volumes of gas were created in the gas syringe and they were recorded as were the corresponding values of pressure at that particular volume. The volume was varied between 20cm3 and 75cm3. Results A set of readings was obtained

Role Playing and its Toll In “The Stanford Prison Experiment‚” psychologist Philip G. Zimbardo describes his study of how placing average‚ male‚ college students in a prison like environment proved that their roles dehumanized them as individuals by radically changing their perceptions and behaviors. Before the experiment‚ the subjects were “emotionally stable‚ physically healthy‚ mature‚ law-abiding citizens” (734). With the flip of a coin ten men were chosen to be prisoners and eleven men

Psychology Experiment No. 2 Effect of Inconsistency of Objects in Scenario on Perception Introduction: In our everyday lives‚ we are used to seeing objects within their particular characteristic scenarios. For example‚ it is nothing to wonder if we see a person browsing the internet in a computer lab or a car speeding on a road. However‚ when we see an object which is inconsistent with the environmental setting‚ we do feel alarmed. Thus‚ it is shocking for us to see someone working on a

Introduction In physics we must distinguish between vector quantities and scalar quantities. Vectors are quantity that has both magnitude and direction. It is typically represented by an arrow whose direction is the same as that of the quantity and whose length is proportional to the quantity’s magnitude. Although a vector has magnitude and direction‚ it does not have position. That is‚ as long as its length is not changed‚ a vector is not altered if it is displaced parallel to itself. In contrast

Dr. Heidegger’s Experiment 5a) The narrative point of view in the story is third person omniscient. This point of view suits the story because; the story catches all the thoughts and emotions of the characters that experience youth through the “fountain of youth”. The narrator seems to be above all the characters‚ expressing how their presence contributes to the storyline. 5b) The external references are people with an outside perspective or background characters that supports the story

The problem for this experiment is how does the amount of caffeine affect the speed and performance of a mouse. The hypothesis is if the amount of caffeine consumed by the mouse is increased‚ then the time at which the mouse completes a set obstacle course will decrease when time is a function of caffeine quantity. The amount of caffeine consumed by the mouse before completing the obstacle course is the independent variable. The dependent variable of the experiment is the amount of time the mouse
