How does the kinetic theory explain Charles 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 are the main postulates of kinetic theory of gases?
9.13: Kinetic Theory of Gases- Postulates of the Kinetic Theory
- The molecules in a gas are small and very far apart.
- Gas molecules are in constant random motion.
- Molecules can collide with each other and with the walls of the container.
- When collisions occur, the molecules lose no kinetic energy; that is, the collisions are said to be perfectly elastic.
Which of the following is the wrong assumption of kinetic theory of gases?
Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams. According to kinetic theory of gases, energy of molecule does not change when they collide with walls of container. So, assumption is incorrect.
Which one of the following is the wrong assumptions of kinetic theory of gases?
Vander Waal pointed out that following two assumptions in kinetic theory are faulty: (i) The volume occupied by the gas molecule is negligible in comparison to the total volume of the gas. This assumption is nearly valid if the pressure is low. (ii) The molecules do not exert any force of attraction upon one another.
What are the postulates of kinetic theory of matter?
The kinetic molecular theory of matter states that: Matter is made up of particles that are constantly moving. There are attractive forces between atoms/molecules, and these become stronger as the particles move closer together. These attractive forces are called intermolecular forces.
What are the main postulates of kinetic?
The kinetic-molecular theory of gases can be stated as four postulates:
- A gas consists of molecules in constant random motion.
- Gas molecules influence each other only by collision; they exert no other forces on each other.
- All collisions between gas molecules are perfectly elastic; all kinetic energy is conserved.
What is success of kinetic theory?
It has been remarkably successful. It gives a molecular interpretation of pressure and temperature of a gas, and is consistent with gas laws and Avogadro’s hypothesis. It correctly explains specific heat capacities of many gases.
