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

Throughout the years‚ many sociologists have researched the conformity within society. The two experiments that remain important and significant are the Asch Experiment and the Milgram Experiment. Both of these experiments researched the basis on why or even how conformity appears in society. The Asch Experiment was an experiment that was done by Soloman Asch in 1951 that took students from Swarthmore College to test if one participant would conform to the majority’s opinion‚ even if the answers

Stanford Prison Experiment Give a basic (introductory only) overview of the study and what occurred • Professor Zimbardio sought to investigate how situational variables impact human behaviour‚ the Stanford Prison Experiment focuses on the roles of ‘guard’ or ‘prisoner’. • During the experiment the guards became increasingly abusive‚ and the prisoners began to show signs of extreme stress and anxiety. • Even professor Zimbardo exhibited the mindset of a prison warden in the experiment. Outline the

Combustion of Gummy Bears Energy is a concept.� Most definitions of the word energy fail to provide its exact meaning when applied to scientific matters.� In science the word energy is a concept that expresses two measurable properties‚ heat and work.� Here is the relationship of energy‚ heat and work: Energy Released=Work Done + Heat Released The Law of Conservation of Energy‚ derived from centuries of observation and measurement‚ indicates that energy cannot be created or destroyed. But energy

Experiment 10 – Enzymes Enzymes are proteins that act as catalysts for biological reactions. Enzymes‚ like all catalysts‚ speed up reactions without being used up themselves. They do this by lowering the activation energy of a reaction. All biochemical reactions are catalyzed by enzymes. Since enzymes are proteins‚ they can be denatured in a variety of ways‚ so they are most active under mild conditions. Most enzymes have optimum activity at a neutral pH and at body temperature. Enzymes are

experiences in history was the Tuskegee experiment. In Macon County‚ Alabama the Public Health Services along with the Tuskegee Institute started a study in 1932 and continued for about 40 years. It was a research study that involved 600 men which 399 had syphilis and 201 didn’t. The purpose for this study was to record the natural history of syphilis in blacks which was called the “Tuskegee Study of Untreated Syphilis in the Negro Male” (CDC‚ 2009). In the 1900’s they did not receive which is known

Becca DeHaven ChemC-125 Avogadro’s Law Experiment Report Introduction: The following experiment’s purpose was to confirm Avogadro’s Law and experimentally determine the Universal Gas Constant “R”. Amedeo Avogadro hypothesized that all gases of equal volume‚ temperature and pressure would contain equal amounts of moles. This idea that volume is directly proportional to moles sprung from other similar hypotheses. Robert Boyle found that pressure and volume are inversely proportional‚ meaning as pressure

It’s about a man named Robert who travels 20 years ahead in time to find out if he had invested his money well. He tells his wife he’ll be back in five minutes‚ but instead she waits for 20 years for his return. When he comes back he finds out his wife had spent all the money. He travels back in time to make sure she cannot do that again

Half Life Experiment My hypothesis would be that after each shaking about half of the remaining candies would be logo-up and half of them logo-down. That’s why the shaking represents a "half-life". half-life || total time (sec) || # of undecayed atoms || # of decayed atoms 0 0 100 0 1 5 65 35 2 10 51
