In essence, thermodynamics involves the examination of the internal motions of various body mechanisms; or rather it’s a subfield of natural science that involves heat and its relationship to various forms of energy and work. Therefore, heat becomes an integral and essential component of thermodynamics. Virtually, most of the substances that people encounter with in their day to day life consist of body systems of one kind or the other, that is, they either fall under solids, liquids, gases or even light. It is therefore, unsurprising that thermodynamics is a field in physics that comprises exceptional wide variety of applicability. There are numerous thermodynamic experiments used to demonstrate the movement of energy from one substance to another as a result of varying of temperature. This column shall study two of the four forms of thermodynamic experiments discussed in the past few weeks. One of the study experiment that this column shall detail on is 'the meaning of heat and this shall be illustrated using the calorimeter experiment. The second form of thermodynamic experiment to be studied is the Statistical physics lab and this will be based on the concept of thermal energy of randomly moving molecules with heat used as the mode of transfer. Meaning of heat Heat is defined as a form of energy, sometimes referred as thermal energy capable of passing through an object of high temperature to an object with low temperature. The flow of heat is essentially measured using a device known as calorimeter. This device operates in such a way that it is insulated to minimize the loss of heat to the surrounding. Within some essential temperature variance, it is easy to understand the hotness or coldness of something by simply touching it. However, it is unreliable if you place one of your hands in cold water, and the other into hot water, then you plunge both into warm water. You will note the difference, one hand will detect that the water is hot, while the other will experience some cold. In other aspects, when something is too hot to hold or even touch, we usually get an impression of how hot the substance is by approaching it and detecting the radiant heat it emits. if there is an increase in temperature, the substance glows hot. The major problem with such subjective feelings of heat is that, they are different for various persons. If two hands transmit different messages pertaining the hotness or coldness of a substance, how about a group of people? Obviously, they will report varied responses. In illustrating the flow of heat, an experiment was set up, whereby a pan of water was placed on a hot glowing fire and the temperature observed over time. It was noted that, their was steady increase in time, reflecting the transfer of heat from the fire, up to the moment the water started boiling, whereby the temperature remained constant for a long period. The steam emitted had same temperatures as the boiling water. So, what actually happened to the heat transferred from the fire to the pan of water? It was found out that, heat was needed to change the form of water from the liquid to the gaseous form/steam. In-fact, a high amount of heat is required to change the state of water to steam form, approximately 540 calories per gram. This is far much ...Download file to see next pagesRead More

... Inserts His/her Inserts Inserts Grade (04, 04, Eye on Media Media Sensationalism With the evolution of media in our society people have become increasingly aware about the world around them. It is a source of information for the general audience and at the same time provides a check on balance on governmental policies. But unfortunately media is also confronting some ethical problems like sensationalism. The old way of telling the story ‘the way it is’ has become obsolete. It is vital for a news channel or a magazine to use luring techniques in order to attract customers. Creating unnecessary hype just to increase the viewership of the channel or a newspaper is not justified. Many channels, newspapers and magazines use theatrics... Inserts...

Analysis of Syndicated Column
...?Analysis of a Syndicated Column In order to properly analyze a syndicated column for this particular assignment, I chose to do my analysis based upon the opinion editorial or op-ed column of Charles Krauthammer for the Washington Post entitled “Everything Starts With Repeal”. This particular editorial piece was first published on January 21, 2011 in the Friday issue of The Washington Post. Mr. Krauthammer wrote the article based upon his carefully crafted research of the farce that ObamaCare represented to the American people. The purpose of his opinion piece was to ask his readers to analyze the merits of keeping the ObamaCare law as it was versus the reality of what would happen to the...

...?Insert of Thermodynamics The laws of thermodynamics are a set of four laws developed to come up with an explanation for the variations in the physical quantities of heat. Thermodynamics on the same note is a branch of physics which deals with the transfer of heat on substances of various types and materials. This is set of three laws each explaining the behavior of heat in certain materials. The basic thermodynamics variables are temperatures, heat and entropy. The three variables are the physical quantities that keep on changing from one material to another depending on the surrounding conditions around the material. A physical quantity is defined by the sequence of operations used to determine its value (Wiliamson... of Thermodynamics The...

The streets appear brighter during the night despite the surrounding darkness in the place where we might happen to be in. More fascinating occurrences often hallucinate our understanding with regard to how certain things operate. Even the most common things such as cell phones which we use in our everyday lives sometimes pose a lot of questions in our minds concerning how they actually operate. We have to charge our cell phones whenever they are exhausted of energy/power. This we have to do by using electricity and we wonder how electricity and the cell phones are related such that we... of...

Vertebral Column Degenerative Diseases Vertebral Column Degenerative Diseases Vertebral column degenerative diseases entail a group of conditions or disorders involving loss of the typical configuration and functions of the intervertebral disc or spine. Although commonly associated with the effects of aging, the diseases may also be caused by arthritis, muscle strains, tumors or infection (Hiwatashi, Danielson, & Moritani, 2004). In between the bones that make up the spine are discs made up of fibrous tissue, cartilage and water. As years advance, the discs tend to weaken and flatten, signifying the onset of degeneration. The intervertebral disc degeneration is characterized by herniations, bulging, spinal stenosis, fissures... , and...

Pivot Column
...Running Head: THE SIMPLEX METHOD – PIVOTS The Simplex Method: What is a pivot column, pivot row and pivot element? In the simplex method, how is a pivot column selected? A pivot row? A pivot element? Give examples of each. The simplex method, or simplex algorithm as it is also known, is an algorithm used for linear programming. Although simplices are not used in the method, it has been suggested that is operates on simplicial cones, hence the name. Pivot operations are a geometrical process that moves from a basic feasible solution to a second adjacent basic feasible solution. If you take a pivot element (non-zero) in a non-basic column, and then multiply the row that the pivot element is in by its reciprocal then you end... up with a...

Wetted wall column
...Wetted column TO STUDY THE EFFECT OF REYNOLD’S NUMBER ON MASS TRANSFER COEFFICIENT SUMMARY The coefficient of mass transfer is affected by both air flow rate and Reynolds number. This experiment (wetted column) studied this relationship, and found out that as air flow rate increases so does the mass transfer coefficient. Also, as the Reynolds number increases so does the mass transfer coefficient. OBJECTIVES One of the objectives of the experiment is to investigate how mass transfer coefficient associated with humidification of air varies with the rate of air flow (air flowrate). Another objective of the experiment is to determine the relationship between the Reynolds number (for turbulent flow and...
