kinetic molecular

• Kinetic-molecular (KMT) theory of gases


  A theory developed based on the observations of scientists and formulated by Rudolf Clausius to provide a general explanation of the properties of gases
• Essential points of the KMT theory

  • Gases are made up of microscopic particles (molecules) that are constantly moving in a random pattern
  • Gas molecules are separated by a significant distance
  • For an ideal gas, there are no attractive or repulsive forces between the gas molecules
  • Gas molecules can collide with one another and the container's walls
  • The total kinetic energy of the gas molecules is equal to the absolute temperature of the gas
• If we were to compress all the gas molecules together, the volume would be so much smaller than the volume of the bottle
• As gas molecules collide


  Kinetic energy may be transferred from one molecule to another

  A theory developed based on the observations of scientists and formulated by Rudolf Clausius to provide a general explanation of the properties of gases
• The overall average kinetic energy of the gas molecules may be taken to be constant

• Observations explained by the KMT


  • The smell of the food we are cooking spreads out and fills the kitchen
  • The force that the gas exerts on a surface is measured as pressure
• The overall average kinetic energy of the gas molecules may be taken to be constant

  • The force that the gas exerts on a surface is measured as pressure
• Speed is measured in meters per second (m/s).
• Average velocity = displacement/time
