Heat and the Kinetic theory of matter - Essay Example From the very basics of what employs the chemical subject, it is imperative that all chemistry students develop a deep understanding of what is the kinetic theory of matter and how it is particularly influenced by changes in the heat and temperature around the substances that are being examined as practical objects. The most understanding decisive factor about understanding all of this is by comprehending the fact of exactly what heat is and how it potentially operates. Heat on with reference to (Encyclopaedia Britannica Educational Corporation. (1989). what is heat?) is the amount of thermal energy that is being possessed by all and every matter established in the universe. To be technically precise the universe as we have come to know is made up of molecules and atoms that are in constant random motion or they fundamentally vibrate about their fixed position causing a stir up in the heat generated or more precisely causing an increase in the thermal energy of their employed surroundings. Thermal energy as being energy is measured in joules and due to the free flowing nature of matter pertaining to the everlasting vibration and motion of atoms and molecules is also passed from one particular body to another and this transfer of thermal energy is known as the exo/endo thermic processes involving the heat transfer of objects. In these cause of events, either endothermic or exothermic there is always a shift in the thermal energy gained or lost by one isolated object to another or vice versa. Generally speaking endothermic and exothermic reactions account on the comparison of heat gained or lost to the surroundings as the environment helps keep one end of the deal at constant r.t.p. (room temperature and pressure) helping in determining which reactions are more active than others. Let us now take a very common example regarding a much general chemistry case that involves either exothermic or endothermic reactions. On significant terms endothermic reactions are rather slow in nature generally than exothermic reactions and hence they ought to have a more time consuming practical approach. Photosynthesis, the using of sunlight in making food for the plant by the plant is an active example of how endothermic reactions occur. Definitive terminology puts endothermic reactions clas sify these as processes in which heat or thermal energy is taken from the surrounds and transferred into the reaction mixture or let us say that thermal energy is gained hence causing a flow in heat from one object to another while decisively in a exothermic reaction such as mixture of sodium chloride to create a salt NaCl is a much faster chemical reaction but in such reactions thermal energy is lost from the reaction mixture into the surrounds i.e. to say that heat, unlike the endothermic reactions, is transferred from the reaction mixture to the surrounds. I personally believe that the study of heat and matter is relatively one of the larger branches of study in the chemistry subject but as so much to this thesis I clearly see that heat and how it is manipulated is been thoroughly achieved through this literature. Moving on to what potentially temperature might be, well temperature on account of Sullivan, N. (2007) is the average heat or thermal energy in a substance. Unlike ther mal energy temperature has more focus on a number
