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

Advice Column from the Washington Post Simon and Bernice

...The first advice column examined was the case of “Simon” and “Bernice”. A woman married Simon when she was five months pregnant. At the wedding Simon’s mother, Bernice, stood up and denounced the writer and her son as only getting married because the writer was pregnant. Other confrontations include a hospital visit where Bernice announced that the writer trapped her son with this pregnancy. After being disinvited to her own husband’s graduation party, the writer told her husband to handle situation. He replied that he could not control his mother’s actions. The writer threw him out, but wonders if she can save her marriage. The writer in this piece acted the way she did due to many reasons. The reason she got married probably was she...

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...

Batch Distillation Column

...BATCH DISTILLATION COLUMN BATCH DISTILLATION COLUMN Summary Distillation is a process that is vital in the separation of liquid mixtures. This process can be conducted in either a continuous or discontinuous manner. That the latter is the basis of batch distillation. In batch distillation, the apparatus for use are loaded with the mixture to be separated at the start-up time. Different fractions of the mixture are then taken out one after another that is in batches, thus giving this process its name. The batch operation is divided into two periods, which describe the entire process. These are; the start-up period, and the production period. A single batch column is able to separate a multi-component mixture in a single operation, to its...

Read the column by Eugene Robinson about the Trayvon Martin shooting. Summarize the main point he is trying to make, and discuss how he uses history to make his point

... Summary and discussion of Eugene Robinsons article about the Trayvon Martin shooting According to Eugene, the much dreaded racism everybody wants to pretend no longer exists is still in action. Racism towards the black society especially the male counterpart still exists. He emphasizes the nature in difference between racism in the past and the presaent times. In the past, there were certain rules and roles in the society that pertained to race unlike at present where there is equality. One would know what, and when to avoid something, while sanctioned assassinations and terrorism were policy reforms. At present, law and society permits equal rights to all races within the society and the occurrence of such a racist act becomes... Summary...

Portions of the Spinal Column

...Portions of the Spinal Column Cervical Spine- This is the uppermost segment of the spinal column. It is composed of seven vertebrae which are numbered from top to bottom as C1 to C7. The first two (C1 and C2) are tailored to provide for neck movement (Wilke, 2006). C1 is found between the skull and the remaining portion of the spine. C2 is distinguished by a bony projection (also known as the odontoid process) which fits in a hole in C1 to facilitate the rotation of the neck. Thoracic spine- This segment has 12 vertebrae (T1 to T12) and is located in the chest section. The ribs are usually attached to the spinal column on the thoracic vertebrae. According to Wilke (2006), the thoracic spine has a curve that bends outwards, forming...

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 laminar flow) and mass transfer...

SQL Server Column Level Encryption

... SQL Server Column Level Encryption Problem Research firms have sensitive information and data that they must protect for two major reasons. Firstly, sensitive data can be harmful to the company’s investment if it is accessed by rivals or unauthorized personnel who can use it against the firm. Identically, exposure of sensitive data to unauthorized personnel is harmful to the parent firm as it may suffer from corporate espionage. Additionally, sensitive data may trigger other research firms to implement their replica research findings prior to the parent’s firm implementation thus leading to losses due to under par returns. Even though firms try to encrypt data with various methods and keys, it has been noted that these companies...
