Kinetic Molecular Theory Gases

Kinetic Molecular Theory Gases. Gas, liquid and solid. KMT of gases. Gas particles are so small their size is insignificant. There are no attractive nor repulsive forces between gas particles. The particles are in constant random motion. All collisions are completely elastic.

  1. Kinetic Molecular TheoryGases Gas, liquid and solid

  2. KMT of gases • Gas particles are so small their size is insignificant. • There are no attractive nor repulsive forces between gas particles. • The particles are in constant random motion. • All collisions are completely elastic.

  3. Translational motion

  4. Gas Pressure • Gas pressure is defined as the force exerted by the gas particles on the walls of its container. • Pressure = • Force/ Area

  5. Atmospheric Pressure

  6. Air pressure and Air density

  7. The 777 wing uses the most aerodynamically efficient airfoil ever developed for subsonic commercial aviation. This advanced wing enhances the airplane's ability to climb quickly and cruise at higher altitudes than competing airplanes while achieving higher cruise speeds. It also allows the airplane to carry full passenger payloads out of many high-elevation, high-temperature airfields.

  8. Why is the design of the wing so important? • What occurs as the plane ascends? • The air gets colder. • The air gets thinner. • There are fewer air particles for the airplane wing to use for lift.

  9. Vacuum • Empty Space with no gas particles. • Not this vacuum • This kind

  10. One Standard Atmosphere • To measure Atmospheric Pressure we have several devices.

  11. Mercury Barometer

  12. Barometers

  13. Gas molecules at different temperatures
