Question

list examples that you have seen in everyday life that is explained by Kinetic Molecular Theory

Answer 1

The main postulates of kinetic-molecular theory are following: All gases are composed of small and widely separated molecules or atoms. The volume of gas is very high compared to its particle's volume. The air in a hot air balloon is heated to make the balloon rise, because Gases move faster at higher temperature, because at high temperature gases particles have greater kinetic energy. As the result the density og gas sample became less which causes it to rise until its density becomes equal to the surrounding atmosphere. All molecules or atoms of any gas behave independently of one another. The motion of each particle (atom or molecule) of gas is in rapid and straight line. It will change with collision with other particles or container wall. Gases move faster at higher temperature, because at high temperature gases particles have greater kinetic energy. As the result they move faster at higher temperature. The total pressure of gas is the sum of the collisions of particles (atom or molecule)) with the wall of container. Gases can be compressed much more than liquids or solids because the distance between the particles of gases are more thus they can be pushed closer together and still remain a gas. 5. The average kinetic energy of gas particles depends only on the temperature of gas. At given temperature, the average kinetic is constant for all gases. The gases particles are very far apart which means that the mass of a gas in a certain volume is very small as the result of this the density the Gases have low densities KE , = = m(V.)? Here, m is molar mass and vis average velocity of gas. We can smell the odor of cooking onions far away because smell the odor of cooking onions is gas and the particles of gases move rapidly in a straight line. As the result it reaches the person who notices its ordor. Example of kinetic theory A container of nonstick cooking spray explodes when thrown into a fire because at the high temperature, there are so many of collision on the container walls and gaseous particles with greater velocities. As the result of this the pressure will increases and the container can endure then the container will explode.
