What does kinetic theory of matter means
There are some characteristics of kinetic energy; among these is a rule that heat transfers occur from the hotter body of matter to the colder matter and not the other way around, unless energy is expended against the natural process (from hot to cold). Relationship of heat to kinetic theory – the importance of this relationship is that kinetic energy in the form of heat can be utilized to operate machines and perform some kind of work. A close understanding of the kinetic theory of matter led to the formulation of the three laws of the theory of thermodynamics today, which are the following: the first law states that energy cannot be created or destroyed but merely converted from one form to another form (an example will be heat energy converted to electrical energy) and in a closed system, energy is always conserved; a second law states that a closed system has entropy or a state of disorder, and the tendency is to be moving towards a state of order or equilibrium (or into a state of inert uniformity) and the second law is sometimes called as the law of entropy; the third law states that the entropy of any system is to approach a constant value as the temperature approaches to zero.
What is temperature – it is merely a number used to measure the amount of heat or the energy present in a substance. Put another way, temperature is not a form of energy, which may be a bit confusing to some people. Temperature is related to energy in some other
way, in that it is used to measure the amount of energy in the form of kinetic energy of a substance. ...
Further to this, the theory makes it understandable the inter-relationships between work, heat, pressure, energy, pressure and volume (applicable to the gaseous state of matter) and the use of these principles. A good application of this theory in practical terms is that heat is not some form of substance but it is rather a form of energy (kinetic energy derived from the motion of atoms and molecules) and as such, can be converted to mechanical energy (Cassidy, Holton & Rutherford, 2002, p., 293). What is heat – it is actual energy as measured in joules or some other form of measure, such as in energy units. In short, heat is the amount of energy in a substance. If one adds energy to a substance, it becomes hotter as a result of that action. Conversely, if you add heat to it, then the substance acquires more energy in the form of kinetic energy of the atoms and molecules. In other words, heat as energy can be used to break the bonds between molecules, as in the case of heat used to melt ice (solid) into a liquid but kinetic energy has not been increased in this case. If heat as energy is added to a substance, two things can happen which are the matter will change in its state (as cited earlier, from solid ice to liquid water without an increase in its temperature, or there is a rise in temperature, such as when water is heated so that it reaches the boiling point). What is temperature – it is merely a number used to measure the amount of heat or the energy present in a substance. Put another way, temperature is not a form of energy, which may be a bit confusing to some people. Temperature is related to energy in some other way, in that it is used to measure the amount of energy in the form of kinetic energy of a substance. It is
