Kinetic theory & it's main points
*Introduction* The kinetic theory is so named because it deals with property of particles which is so crucial in understanding the three states of matter namely the motion of particles . Because the particles are in constant motion , they possess kinetic energy which tends to keep the particles well spaced out in any substance . This in terms of kinetic energy . *Main points * 1= The gaseous state is the one in which the molecules are widely separated from one another but having negligible volume . The gases are easy to compress due to large empty spaces . 2= The gas molecules are in continuous motion , traveling in straight paths between collisions , but in random directions . The average distance between collisions is the mean free path . 3= The molecules collide with one another and with the walls of container , but these collisions are perfectly elastic ( result in no loss of energy ) 4= In an ideal gas , there are no attractive or re...
