er. ... The higher the temperature, the greater the motion.There are three main components to kinetic theory: No energy is gained or lost when molecules collide. The molecules in a gas take up a negligible (able to be ignored) amount of space in relation to the container they occupy. The molecules are in constant, linear motion.The model, called the kinetic theory of gases, assumes that the molecules are very small relative to the distance between molecules. The molecules are in constant, random motion and frequently collide with each other and with the walls of any container. ... The higher the temperature, the greater the motion.The kinetic-molecular theory of gases assumes that ideal gas molecules (1) are constantly moving; (2) have negligible volume; (3) have negligible intermolecular forces; (4) undergo perfectly elastic collisions; and (5) have an average kinetic energy proportional to the ideal gas's absolute temperature.Kinetic gas equation can also be represented in the form of mass or density of the gas. It is based on the postulates of kinetic theory gas equation, a mathematical equation called kinetic gas equation has en derived from which all the gas laws can be deduced. It is usually written in the form: PV = mnc2.
