Temperature. PV = nRT. Both sides of this equation have dimensions of energy.
n = number of moles; R is the Ideal Gas Constant; and T is absolute Temperature. So for a given amount of gas, the energy is directly proportional to Temperature.

Does kinetic energy increase with size?
Velocity of molecular movement is lower in larger molecules because it takes more energy to get the larger molecule moving. On the other hand, smaller molecules move more rapidly causing its velocity to be higher.
Temperature is relative to the energy of the molecules?
Increasing temperature will increase molecular speed.An object with less massive molecules will have higher molecular speed at the same temperature.When kinetic temperature applies, two objects with the same average translational kinetic energy will have the same temperature. An important idea related to temperature is the fact that a collision between a molecule with high kinetic energy and one with low kinetic energy will transfer energy to the molecule of lower kinetic energy.
Which process can be explained by the kinetic-molecular theory?
Diffusion can be explained by the kinetic-molecular theory.
Does kinetic energy increase with speed and time?
Time is not a factor, speed is velocity and velocity equates to kinetic energy. E=Mass * Velocity squared.
Do changes in velocity and mass have the same effect on kinetic energy?
Kinetic energy is equal to one half the mass times the square of the velocity. Thus, changes in velocity and mass do not have the same effect on kinetic energy. If you increase the mass by a factor of 10 at the same velocity, you increase the kinetic energy by a factor of 10. However, if you increase the velocity by a factor of 10 at the same mass, you increase the kinetic energy by a factor of 100.
Does velocity of molecular movement reflect kinetic energy?
no

What determines speed?
Temperature is a major determinant of molecular velocity. By applying heat to a system molecular velocity increases, as does pressure and kinetic energy. The two physical and chemistry equations of the Ideal Gas Law and calculating kinetic energy through mass and velocity illustrate this relationship mathematically.
Kinetic energy is directly related to?
it is directly related to the weight or mass of an object

What is the abbreviation for kinetic molecular theory?
Kinetic Molecular Theory's abbreviation is KMT or sometimes KMTG when it is the abbreviation for Kinetic Molecular Theory of Gas
What is the definition of kinetic molecular model?
Kinetic Molecular Model?? kinetic molecular model,which describes the behavior of solids,liquids and gases,was established based on the kinetic molecular theory. :)) SOURCE?. mah book^^ ♥
What property of a gas molecule affects the speed at which it diffuses?
The most important is the molecule diameter.
Which process can be explained by the kinetic-molecular theory?
Diffusion can be explained by the kinetic-molecular theory.
What happends to kinetic energy when the velocity increases?
Kinetic energy is proportional to the square of the magnitude of velocity.
What moves faster large molecules or small molecules?
given the same amount of kinetic energy a smaller molecule would have a high velocity according to k=mv^2
How do you know which molecule has the greatest speed at STP?
Temperature measures kinetic energy on a molecular level, and kinetic energy depends upon two things, speed and mass. So, if the temperature is a constant (since you have specified STP) the lighter the molecule is, the faster it will be moving. The lightest molecule, of course, is hydrogen. So hydrogen moves the fastest of any molecule at a given temperature.
