No. There is a well known distribution of probabilities that describes how likely it is that a given molecule has a given kinetic energy, but a gas will always have some fast and some cold molecule. The average KE is defined by temp, however.

∙ 11y agoNO - the molecules in a sample of gas are expected to have a Maxwell-Boltzman distribution of velocities. There is a finite probability for molecules to have any particular speed, from zero to near-lightspeed, but the probabilities of those speeds are described by the Maxwell-Boltzman distribution. As the internal energy of the gas increases, the mean velocity increases. In theory all the molecules could have that same mean velocity, but the probability is so incredibly small that even for a very small gas sample you would never expect to observe such a phenomena during the life of the universe.

What is relation between temperature and molecular vibration of an object?
Heat energy in a substance is the intensity of vibration of the molecules in that substance. The more the vibration more is the heat energy stored in the object. So in a way Heat energy is the kinetic energy of the molecules in the substance. Thus temperature increases on the increase in the kinetic energy of the gases.
Do molecules in a liquid have the same kinetic energy as a gas?
Less kinetic energy to move around so they stay liquid. With more energy they would be gases.
Which has kinectic energy solids or liquids or gases?
Any of them can have kinetic energy - which is the energy "stored" in movement. So, a solid object moving has kinetic energy. In liquids and gasses, the atoms / molecules that make them up are in constant motion too, so they have a little kinetic energy as a result.
The molecules of all samples of ideal gases have the same average kinetic energies at the same?
Temperature and pressure.KEavg = (3/2)RT
Why does heated gases became lighter?
Higher temperature results to higher kinetic energy in gas molecules. The gas with more speed would bounce each other a further distance and thus the expansion of gas.
Two different gas with different density when heated in same temperature will the state of expantion of the two gases be the same.?
Yes. because expansion depends upon kinetic energy of the molecules and at same temperature the molecules of both the gases have the same average kinetic energy.
Why do all gasses exert pressure in terms of KMT?
Pressure is the effect of collisions with molecules. KMT -- molecules have kinetic energy due to their temperature which imparts more velocity, hence kinetic energy, to the molecules. All gases have KE due to temperature. IF absolute zero was ever achieved there would be no kinetic energy in the molecules, no molecular motion, no collisions, no pressure.

When heat is supplied to molecules their which energy increases?
In gases their kinetic energy rises
What gases have in common?
All gases have same kinetic energy of molecules at same conditions.
How does kinetic energy of solids liquids and gases compare?
The kinetic energy is lowest in solids, higher in liquids, and highest in gases.
Do molecules move more and move apart as temp increases?
As temperature increases, kinetic energy of the molecules increases also, making the molecules move faster and move apart if they are able, as in fluids and gases.
Do molecules in a liquid have the same kinetic energy as a gas?
Less kinetic energy to move around so they stay liquid. With more energy they would be gases.
The kinetic-molecular theory explains the behavior of?
The Kinetic Molecular theory is used to describe the behavior of gas. It gives the relationship between pressure, temperature and kinetic energy.
How does the kinetic energy of solids liquids and gases compare?
Gases have the highest kinetic energy, followed by liquids, and then solids. -apex
What would be the kinetic energy of particles of gas when it compressed in a cylinder?
When a gas is compressed, its temperature tends to increase. That means that the average kinetic energy per particle also increases.
What is the effect of temperature on molecules?
The higher the temperature, the more rapid the molecular motion.When the temperature rises (such as in water), the molecules move faster. When they cool, they slow down. That's how water boils.
