Kinetic Molecular Theory - is a model that is used to predict gas behavior . States that gas particles are in constant rapid, random motion . States that the particles of a gas are very far apart . This idea explains the fluidity and compressibility of gases. Gas particles in constant motion collide with each other and with the walls of their container. Theory states that the pressure exerted by a gas is a result of collisions of molecules against the walls of container. Energy is completely transferred during collisions. Total energy remains constant -Conservation of Energy. The average kinetic energy of random motion is proportional to the absolute temp, or temp in Kelvin. Heat increases the energy of motion , so not all molecules are traveling at the same speed. Gas particles moving faster at higher temps, hit the wall of the container with more force. It explains only physical properties P =pressure exerted V =volume occupied T =temperature in Kelvin (syn. Is absolute temp.) N =# of moles/quantity Kelvin=C+273
