Explain Gas Laws through Kinetic molecular theory
why water has low vapour pressur and high surface tension Ok, well the answer to your first question is hydrogen bonds. Water has high surface tension and low vaporization temp because the hydrogen bonds in water make strong dipoles that are difficult to separate (yielding high surface tension) and greater energy to overcome when vaporized. study help site http://ocw.mit.edu/courses/physics/8-01-physics-i-classical-mechanics-fall-1999/syllabus/ Explain gas laws through KMT acc to k.m.t gasses molecules are widely separated and when pressure is applied there molecules come closer by which the volume is decrease(temperature must be constant)
CHARLE'S LAW
acc to k.m.t the molecules of a gas posses kinetic energy which is directly proportional to temperature(at constant pressure) and when the temp is increased kinetic energy also increases due to which the sample of a gas expands in order to keep its pressure constant and volume increases
AVOGADROES'S LAW
acc to k.m.t when two gasses have same temperature their kinetic energy is same,so they exert same pressure because molecules collide with same forcebut pressure also depends upon the number of molecules collides with the walls of container .. thus if the gases have same T and same P means they posses same number of molecules.
DALTON'S LAW
acc to k.m.t there is no attraction between gas molecules .hence in a mixture of gasses ,each gas behaves independantly ,molecules of each gas on colliding with the walls of container produces their own pressure hence the total pressure is the sum of partial pressur of individual gasses
In Formation of Nacl Crystal Lattice, the enrgy changes is explained by Born-Haber Cycle. First, sublimation of Na requires energy, then energy is required for breaking the Chlorine molecule into chlorine atoms....Now, more energy is required to ionize the Na atoms. This energy is called Ionization energy. Now, when these electrons get added to chlorine,
