Kinetic Molecular Theory of Gases Gases consist of molecules that are constantly moving through space in strait lines, randomly, and with various speeds

Kinetic Molecular Theory of Gases The average kinetic energy of the gas molecule is proportional to the absolute (K) temperature Meaning: the higher the temperature, the faster the gas particles move

Kinetic Molecular Theory of Gases The gas molecules collide with each other without loosing any kinetic energy – like billiard balls

Kinetic Molecular Theory of Gases The molecules volume is tiny compared to that of the container – the assumption that in comparison the gas molecules take up not volume is used

Kinetic Molecular Theory of Gases Gas molecules have no attraction between themselves

Kinetic Molecular Theory of Gases The collisions against the sides of the container constitute the pressure of the gas
