In discussion one, the paper describes how proximity between objects affects the conduction of heat in the matter. The assertion that conduction occurs when objects are in contact is a very clear explanation of the process; it is also crucial to note that conduction does not occur in gases or liquids. It is admirable how the work defines heat conduction using a very simple approach; I like the fact that the definition of conduction in the discussion is concise.
In addition, the work has outlined the relationship between convection as a method of heat transfer and the motion of objects. For the reader, this aspect of relating phenomena leads to clarity of the information that is intended for the audience.
Electromagnetic radiation may be a new term to the reader of the paper, but the writer has gone a step further to note down the examples of these electromagnetic radiations. This is quite impressive in the work. It practically synthesizes the scientific jargon contained in the paper into very simple terms that can be understood by nonprofessionals.
While discussing the scientific fact behind the process of radiation, the paper mentions that during the process of radiation, there is no requirement of matter between the objects in question. This is a very convenient style of reporting, it focuses on details so that the reader is given plenty of details to assist in understanding the concept under discussion.
The work has fully embraced the pedagogical model of teaching from known proceeding to unknown then. In the first paragraph, methods of heat loss are discussed; the subsequent paragraphs then focus on the operational model of a flask. I find this quite easy to comprehend. After discussing convection, radiation, and conduction, the reader is exposed to the Thermo flask and its model of operation. Systematic learning is employed in the work by first addressing the technical terms before engaging the reader in the practical parts.
The introductory part of discussion 2 gives the historical background of the object under discussion. This is quite remarkable of the work as the chronological origin of the object is mentioned. For a reader, the understanding of the object is enhanced. I find it easy to grasp the content under discussion when this style of writing is used. The description of how flasks came is incredible.
The work makes a commendable contribution by relating the scientific concept of radiation, convection, and conduction to the operation of the Thermo flask. I find the second discussion quite practical in its approach to the topic at hand. It deviates from theory and shifts focus on the practicality of the theoretical concept of how a flask works. The manner, in which the writer defines the three scientific principles: conduction, convection, and radiation, openly focuses on explaining how the Thermo flask operates. Discussion 2 thus becomes very adequate in studying how flasks work, with a tinge of expediency.
My main concern with discussion 2 is that it does not give a detailed theoretical approach about the flask weight; however, it is very successful in addressing the manner, in which the object works. The improvement models of the Thermo flask as illustrated in discussion 2 are quite remarkable, they give the reader a much-advanced understanding of the flask and its flaws.
