Kinetic theory – this particular theory says that all three states of matter (gases, liquids and solids) possess some energy resulting from the constant motions of the atoms and molecules that comprise matter. This energy from motion is called as kinetic energy…

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

Later, Albert Einstein described the motion through what came to be referred to as the molecular theory of matter, also referred to as kinetic theory of matter. This postulates that all matter would be constituted of tiny particles referred to as molecules which constantly move and bounce off each other just like the billiard balls.
This essay explores the differences between heat and temperatures. The researcher of this essay aims to pay special attention to properties of a substance that determine its heat capacity. The properties include the following: quantity; viscosity; size and conductivity. This essay also analyzes sources of heat such as solar energy; earth; burning fuels; electricity.
In the latter literature presented therein, we would fundamentally look into various methods and definitions employed to exactly what heat and temperature are with regards to the kinetic theory of matter and how they particularly influence this law.
Heat transfer occurs from a substance or objects that is warm to a substance or object that is cooler. Scientists measure heat energy using the ordinary unit of energy, the Joule (Sullivan & Edmondson 2008). Nasser (2009) adds that the movement of heat energy happens from a system to the other.
A better understanding of heat includes responding to the following questions.
The study of heat relates to kinetic theory of matter by considering the characteristics surrounding matter and its relation to heat production. The kinetic theory
There are three states of matter namely solids, liquids and gases. This theory states that matter is composed of particles that are in constant motion. These particles are either atoms or molecules. The particles
Heat is a form of energy which created by the motion of atom and molecules. Atoms and molecules are engaged in random motion inside all matters. In solids these motions are small and hence solids have a finite shape. On the other hand in liquids and gases these atomic and molecular motions are large and hence it is difficult to assume particular shape to liquids and gases.
As stated by the theory, matter is made up of tiny particles called molecules or atoms that move in motion. Solids have particles that are compactly bounded to each other that can cause vibration movement rather than moving from one location to another. Kinetic theory can also be used to describe the many physical states of matter.
According to the theory, matter is composed of a number of small particles that are called atoms or molecules and these atoms or molecules are always in movement and their movement is multidirectional. Study is heat is related to kinetic theory of matter as heat is a process in which, thermal energy shifts from one object to the other and the movement of molecules get faster with shifting of thermal energy.
