* Kinetic Theory of gases. This Theory is based on Many assumptions. Any yus contains Molecules which are identical in all respects but differ from those of other gases. have No Attractive dr repulsive forces, and which ove in Constant random motion. The volume occupied by the Molecules May be Neglected in comprison to the Total Volume. The average kinetic energy [m²] of a molecule is directly proportione to the temperature of the gas. The gas molecules are assumed behave like rigid spheres which Colloide with each other and the walls of the container of Cubic geometry with the length of each side equal. Lo The velocity & May be resolved into Components M, V, W Parallel to the twer mutually perpendicule axes x, y, z velocities aluny the thice axes. in un imaginary Cubid side C²=M²+V²+w² 2 2 2 2 Collisions are assumed to be perfectes elastic so that After a collision. the velocity does Not Change, only the Direction. if the Mass is Nom +m/4l to , Mumentum Cherges -m|씨 where IM) is just Absolute value Change in Momentum 2m/세 2mm() = 2m² a = 2(Nm) a 2 2NmM² = NMM 9.242 P =
