The five basic ideas of kinetic molecular theory are:
- The volume occupied by the gas molecules should be negligible when compared to the volume of gas
- The collisions should be perfectly elastic
- The molecules of ideal gas should not exert an attractive force
- The average kinetic energy of the gas molecules and the absolute temperature should be directly proportional
- The gas molecules should be in constant random motion.
How does the kinetic molecular theory explain the behavior of gases?
The Kinetic-Molecular Theory Explains the Behavior of Gases, Part II According to Graham’s law, the molecules of a gas are in rapid motion and the molecules themselves are small. The average distance between the molecules of a gas is large compared to the size of the molecules.
What is the kinetic energy of gas molecules?
Gas molecules exert no attractive or repulsive forces on each other or the container walls; therefore, their collisions are elastic (do not involve a loss of energy). The average kinetic energy of the gas molecules is proportional to the kelvin temperature of the gas.
What is the relation between kinetic molecular theory and Graham's Law?
This is the same relation observed experimentally and expressed as Graham’s law. The kinetic molecular theory is a simple but very effective model that effectively explains ideal gas behavior.
How is average kinetic energy related to Kelvin temperature?
The average kinetic energy of the gas molecules is proportional to the kelvin temperature of the gas. The test of the KMT and its postulates is its ability to explain and describe the behavior of a gas.
What is the main concept of kinetic-molecular theory?
The kinetic-molecular theory explains the states of matter, and is based on the idea that matter is composed of tiny particles that are always in motion. This theory helps explain observable properties and behaviors of solids, liquids, and gases.
What are the 4 parts of kinetic-molecular theory?
Explanation: Gas formed by point-like particles ( volume≈0 ); No intermolecualar attractions between the molecules of the gas; Random motion; Elastic collisions.
What are the five basic postulates of kinetic-molecular theory quizlet?
Terms in this set (5)Gases are composed of infinitely small particles.The volume of a gas is composed of the space between the particles.Particles are in a constant random motion.Particles do not gain or lose kinetic energy during collision.Average kinetic energy of the particles is proportioned to temperature.
What are the 3 principles of kinetic theory?
What are the three principles of kinetic theory?...No energy is gained or lost during the collision between molecules.Molecules take up a negligible amount of space in relation to the container space they occupy.The molecules are in constant linear motion.
What are the main points of the kinetic theory of matter?
The kinetic theory of matter (particle theory) says that all matter consists of many, very small particles which are constantly moving or in a continual state of motion. The degree to which the particles move is determined by the amount of energy they have and their relationship to other particles.
What are the main assumptions of kinetic-molecular theory quizlet?
Terms in this set (3)Number One. All matter is composed of tiny particles that are in constant motion.Number Two. The speed of the particles' motion depends upon the temperature.Number Three. The total amount of kinetic energy of the colliding particles remains constant.
What are the assumptions of the kinetic theory?
The simplest kinetic model is based on the assumptions that: (1) the gas is composed of a large number of identical molecules moving in random directions, separated by distances that are large compared with their size; (2) the molecules undergo perfectly elastic collisions (no energy loss) with each other and with the ...
Which is a postulate of the kinetic-molecular theory quizlet?
What is a postulate of the kinetic molecular theory of gases? The particles that compose a gas are so small compared to the distances between them that the volume of the individual particles can be assumed to be negligible.
What is an example of kinetic molecular theory?
What are some examples of kinetic molecular theory? Brownian Motion—the random movement of particulate matter caused by collisions with "air" molecules, and Boyle's, Charles', and Gay- Lussac's Laws—are examples of kinetic theory. This theory also emphasizes how temperature influences the states of matter.
Why is kinetic molecular theory important?
The Kinetic Molecular Theory is essential for the explanations of gas pressure, compressibility, diffusion, and mixing. Our explanations for reaction rates and equilibrium also rest on the concepts of the Kinetic Molecular Theory. Approximately 20% of the atmosphere is oxygen. This gas is essential for life.
How does the kinetic molecular theory of gases explain gas pressure?
The kinetic molecular theory can be used to explain each of the experimentally determined gas laws. The pressure of a gas results from collisions between the gas particles and the walls of the container. Each time a gas particle hits the wall, it exerts a force on the wall.
Who proposed kinetic molecular theory of gases?
The British scientist James Clerk Maxwell and the Austrian physicist Ludwig Boltzmann, in the 19th century, led in establishing the theory, which became one of the most important concepts in modern science.
How many questions are there in Tenets of the Kinetic-Molecular Theory?

Is kinetic energy proportional to temperature?
The Average kinetic energy is proportional to the absolute temperature
Is the combined volume of molecules of a gas negligible relative to the total volume?
The combined volume of molecules of a gas are negligible relative to the total (net) volume
