Question

Write any three postulates of Kinetic theory of gases.

Answer 1

Postulates of the kinetic theory of gas-

• The molecules in a gas are small and very far apart. Most of the volume which a gas occupies is empty space,
  
• Gas molecules are in constant random motion. Just as many molecules are moving in one direction as in any other,
  
• Molecules can collide with each other and with the walls of the container. Collisions with the walls account for the pressure of the gas,
  
• When collisions occur, the molecules lose no kinetic energy; that is, the collisions are said to be perfectly elastic.
