- Temperature is defined as the average kinetic energy of molecules. Most of the space is empty, no molecules, thus the concept of temperature becomes meaningless. The 3 degree K background radiation does not require atoms as most of the space is empty.

- When the average kinetic energy of the molecules goes up (a rise in temperature), the average speed of the molecules increases. And lower average kinetic energy of the molecules means they have lower speed. However, a change in average kinetic energy is not directly proportional to a change in average speed.

- Kinetic energy is related to temperature and the mass and velocity of the molecules (K.E. = 1/2 mv2). When the temperature reaches the boiling point, the average kinetic energy of the liquid particles is sufficient to overcome the forces of attraction that hold molecules in the liquid state.

Kinetic theory of gases The kinetic theory describes a gas as a large number of submicroscopic particles (atoms or molecules), all of which are in constant, random motion. The rapidly moving particles constantly collide with each other and with the walls of the container.Kinetic theory explains macroscopic properties of gases, such as pressure, temperature, viscosity, thermal conductivity, and volume, by considering their molecular composition and motion.he temperature of an ideal monatomic gas is proportional to the average kinetic energy of its atoms. The size of helium atoms relative to their spacing is shown to scale under 1950 atmospheres of pressure. The atoms have a certain, average speed, slowed down here two trillion fold from room temperature.

Ideal Gas Law One mole of an ideal gas will occupy a volume of 22.4 liters at STP (Standard Temperature and Pressure, 0°C and one atmosphere pressure).n such a gas, all the internal energy is in the form of kinetic energy and any change in internal energy is accompanied by a change in temperature. An ideal gas can be characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T).

Gas Molecule Motion Gas Molecule Motion. At a low temperature a gas molecule travels, on the average, at a slower speed than than it would at a high temperature. So, at a low temperature the molecules have, on the average, less kinetic energy than they do at a high temperature.

- Radiation is a form of energy transport consisting of electromagnetic waves traveling at the speed of light. Temperature is a measure of the average heat or thermal energy of the molecules in a substance. The atoms and molecules in a substance do not always travel at the same speed. This means that there is a range of energy (the energy of motion) among the molecules. In a gas, for example, the molecules are traveling in random directions at a variety of speeds - some are fast and some are slow. Sometimes these molecules collide with each other.

What does the kinetic molecular theory state? The Kinetic Molecular Theory states that the average energy of molecules is proportional to absolute temperature as illustrated by the following equation: where ek is the average translation kinetic energy, R is the gas constant, NA is Avogadro's number, and T is temperature in Kelvins. Since R and NA are constants, this means that the Kelvin temperature (T) of a gas is directly proportional to the average kinetic energy of its molecules. Shottsk2002 · 3 years ago 0

- they posses Kinetic energy when collide with surface with the same energy.The collective energy is measured as pressure. Explanation: when molecules of gas or air move they possess certain amount of kinetic energy,by colliding any surface the collective energy the exerts on the surface is measured as pressure . And that is how these molecules cause pressure.

Thus, the average kinetic energy of the gas particles increases as the gas becomes warmer.he Kinetic Molecular Theory Postulates. The experimental observations about the behavior of gases discussed so far can be explained with a simple theoretical model known as the kinetic molecular theory. This theory is based on the following postulates, or assumptions.
