The existence of atoms is universally accepted by the scientific community, as well as by most of the developed world. Atom bombs, nuclear reactors, electron microscopes, electricity, sound, the entire sciences of chemistry, physics, and Biology all serve as proof for the existence of atoms.
The kinetic theory of matter describes how atoms and molecules are in constant motion due to their kinetic energy. While atoms vibrate in place, they also move in random directions at different speeds. This motion is what gives matter its properties such as temperature and pressure.
Yes, atoms have energy. Atoms have kinetic energy based on thermal energy (the "vibration" of the atom) and also on electron motion. They also have the energy of their mass. This is the energy that would be derived if all of their mass was converted into energy. That's the so-called mass equivalence that Albert Einstein gave us with E=mc2.
Not exactly, however you are on the right track, the Kinetic-Molecular Theory can be summarized by the following statements:
- Gases consist of large numbers of molecules that are in constant, random motion. (The word molecule is being used here to designate the smallest particle of any gas; some gases, like the noble gases, consist of individual atoms)
- The combined volume of all the molecules of the gas is negligible relative to the total volume in which the gas is contained.
- Attractive and repulsive forces between gas molecules are negligible.
- Energy can be transferred between molecules during collisions, but the average kinetic energy of the molecules does not change with time, as long as the temperature of the gas remains constant. In other words, the collisions are perfectly elastic.
- The average kinetic energy of the molecules is proportional to the absolute temperature. At any given temperature the molecules of all gases have the same kinetic energy.
Hope this helps...
Yes. All atoms vibrate therefore all atoms are in motion at all times.

Which of the following best describes the kinetic theory?
Atoms and molecules are always moving or vibrating.
What is true about the movement of atoms and molecules?
Atoms and molecules are in constant motion, vibrating and moving randomly. This movement is due to their kinetic energy. In gases, atoms and molecules move freely in all directions, while in liquids and solids, the movement is more restricted.
What is the abbreviation for kinetic molecular theory?
The abbreviation for kinetic molecular theory is KMT.
The kinetic theory of matter states that matter is made of particles whose speed is dependent on what?
The kinetic theory of matter states that matter is made of particles whose speed is is dependent on the temperature of the substance. As temperature increases, the average speed of particles also increases.
What correctly describes an assumption made by kinetic molecular theory?
Kinetic molecular theory assumes that gases consist of particles (atoms or molecules) in constant random motion. It also assumes that gas particles are small compared to the distance between them. Additionally, the theory assumes that gas particles are in continuous, rapid, and random motion.
Which of the following best describes the kinetic theory?
Atoms and molecules are always moving or vibrating.
What is kinetic theory of diamonds?
The kinetic theory states that all matter is composed of tiny particles in constant motion. In the case of diamonds, this theory explains that the carbon atoms that make up a diamond are in motion, vibrating in place but not moving around like in a liquid or gas. This motion gives diamonds their structure and hardness.
What is the kinetic-theory?
The theory that states that all atoms are constantly moving
What is kinetic theory matter?
Atoms+molecules moving around.
What is the summary of the kinetic theory?
Atoms and molecules are always in motion
What describes kinetic theory?
atoms and molecules are always moving
What is the best summary of the kinetic theory?
Atoms and molecules are always in motion
How does the kinetic theory of the matter relate to heat transfer?
Kinetic theory and Heat transfer are both in motion, in Kinetic theory all states of matter are in vigorous motion and Heat transfer is associated with the motion of atoms or molecules.
What is proportional to the average kinetic energy of the atoms and molecules that make a substance?
The temperature of the substance is proportional to the average kinetic energy of its atoms and molecules. The higher the temperature, the greater the average kinetic energy. This relationship is described by the kinetic theory of gases.
What is meant by the term kinetic theory of matter?
The meaning is that atoms and molecules are permanently in motion.
When matter is warmed does kinetic energy increase or decrease?
When matter is warmed, its kinetic energy increases. This is because heating a substance increases the average speed of its particles, leading to a higher kinetic energy.
When rapidly vibrating atoms collide with slowly vibrating atoms causing a transfer of heat?
Heat
