Chemistry and Chemical Reactivity Essay

The Kinetic molecular Theory of Gases (KMT) is an explanation and description of the accomplishment and way of molecules. It looks into the kinematics of molecules, wherein focus on the forces exists among molecules and the energy generated by the motion of these molecules (Poseidon softw ar package and Invention, 1997). Etymologically, the KMT comes from kinetic which means moving, and molecular which comes from the root word molecule, classically the smallest social unit of particle.The KMT includes several postulates which describe how the molecules of gases be put on. The interest atomic number 18 features of how gas molecules behave (1) Gases atomic number 18 composed of very small particles called molecules (2) the molecules are very large in number (3) they are perfectly spherical in shape and whippy in nature (4) their wad is negligible which implies that they can move freely (Dogra, 1984) (4) the average distance between molecules is relatively large as compared to their sizing (Kotz, et al. , 2008) (5) they behave in a state of invariable, random motion following Newtons Laws (Selvaratnam, 1998) (6) they move in a straight notation until they collide with another particle or with the walls of the container (Whitley, 2005, n. p. ).(7) the strikes of the gas molecules with other particles or with the walls of the container are perfectly elastic such that the total kinetic energy later on the collision is equal to the total kinetic energy before the collision (8) in that respect are no attractive or repulsive forces between the molecules, and only during collisions do the particles exert forces on each other (Wulfsberg, 2000) (9) there is no energy lost during the collisions energy is conserved and (10) the average kinetic energy of the particles depends on the temperature of the system.These postulates can be further illustrated in cost of the interpretation of the temperature and pressure of a gas. Temperature, being a macroscopic ch aracteristic of bailiwick, is interpreted in terms of the kinetic energy of the molecules (Selvaratnam, 1998, p. 183). There is a directly proportional relationship between the temperature and the kinetic energy of the molecules of a gas. This means that an increase in temperature travails a similar increase in the kinetic energy or rapid movement of the molecules.The hotter the gas is, the fast its particles move (Whitley, 2005, n. p. ). Pressure, on the other hand, is due to the incessant bombardment of the walls of the container watercraft by the billions and billions of molecules present (Selvaratnam, 1998, p. 183). This only means that if more collisions occur, the pressure is higher. The exclusive gas laws could be put into perspective in relation to the KMT. harmonize to Boyles Law, at constant number of moles and temperature, pressure and volume are inversely proportional (Whitley, 2005, n. p. ).Charles Law, on the other hand, states that at constant number of moles and pressure, the volume and the temperature are directly proportional (Whitley, 2005, n. p. ). A tercet Gas Law consists of the theory that at constant number of moles and pressure, the volume and the temperature are directly proportional (Whitley, 2005, n. p. ). These individual gas laws, if combined, would produce an prototype gas. In relation to the motion of the molecules, the molecular activities in the three states of matter differ in several aspects.In the solid state, the particles are jam-packed in a more closely manner. They are held closely to maven another by their attractive forces (Poseidon Software and Invention, 1997). These strong, attractive forces between the particles cause them not to move freely and instead, vibrate. This feature results in a decisive shape and volume of solids. In the liquid state, the intermolecular forces only get the particles to flow or glide over one another. As compared to solid, the motion of the molecules is more random.The shape and volume of a liquid is dependent on its container. The intermolecular forces are also essential in understanding the disintegration of things. In the dissolving process, the molecules of the solute are surrounded by the molecules of the solvent. Here, molecular bonds between molecules of solute have to be broken and molecular bonds of the solvent also have to be disrupted (Educating Online, 2007, n. p. ).ReferencesBlauch, D. N. (2001).
