What are the 5 postulates of the kinetic-molecular theory of gases?

Five Postulates of KMT.

• Gas particles travel in straight lines unless they collide with other particles or the walls of the container.
• Gas particles have negligible volume compared to the free space between them..
• Molecular collisions are perfectly elastic and kinetic energy is conserved.

What are the postulates of kinetic theory of gases Class 11?

The basic postulates of kinetic theory of gases are: (i) All gases consist of atoms or molecules. (ii) Molecules of a gas are in random motion. (iii)The volume occupied by gas molecules is negligibly small as compared to volume of the container.

What are the main postulates of kinetic theory of matter?

The main postulates of the kinetic theory of matter are:

• Matter is composed of very small particles called atoms and molecules.
• The constituent particles of a kind of matter are identical in all respects.
• These particles have space or gaps between them which is known as interparticular or intermolecular space.

Which of the following postulates of the kinetic molecular theory for gases can explain why gases exhibit pressure?

An increase in the number of gas particles in the container increases the frequency of collisions with the walls and therefore the pressure of the gas. The last postulate of the kinetic molecular theory states that the average kinetic energy of a gas particle depends only on the temperature of the gas.

Which of the following postulates of kinetic theory of gas is responsible for deviation from ideal Behaviour?

The main reason for deviation of gases from ideal behaviour is few assumptions of kinetic theory. These are. (i) there is no force of attraction between the molecules of a gas. (ii) volume of the molecules of a gas is negligibly small in comparison to the volume of the gas.

What is the 3 main parts of kinetic theory of matter?

Terms in this set (3)

• Part 1 kinetic theory. All matter is made up of tiny particles.
• Part 2 kinetic theory. These particles are always in motion.
• Part 3 kinetic theory. Particles with more mass move more slowly then particles with less mass.

Which of these is a postulate of 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. gas particles colliding with the container walls. the kinetic energy of the gas particles.

How can the postulates of the kinetic molecular theory be used to explain the ideal gas law?

Kinetic Molecular Theory states that gas particles are in constant motion and exhibit perfectly elastic collisions. Kinetic Molecular Theory can be used to explain both Charles’ and Boyle’s Laws. The average kinetic energy of a collection of gas particles is directly proportional to absolute temperature only.

What is the kinetic theory model?

The model, called the kinetic theory of gases, assumes that the molecules are very small relative to the distance between molecules. The molecules are in constant, random motion and frequently collide with each other and with the walls of any container. The higher the temperature, the greater the motion.

Which postulate of the kinetic-molecular theory best explains why gases can be compressed?

Which postulate best explains why a gas can be compressed? The particles of a gas are tiny compared with the distances between them.
