Question
Which statement listed below is not part of the kinetic model for gases? An ideal gas consists of molecules (or atoms) in constant, random motion Gas molecules do not exert intermolecular forces upon one another The volume of the molecules is negligible compared to the space between them. The molecules of an ideal gas collide with the walls of their container and with each other. All four of the above statements are part of the kinetic model. To account for the fact that the volume of a gas is directly proportional to its temperature in kelvins, it is necessary to postulate that: There is a distribution of molecular speeds between gas molecules The molecules have negligibly small volumes Molecules collide with each other On the average, molecules move faster at higher temperatures None of these explain this direct proportionalityExplanation / Answer
6) option e is correct
7) option d is correct
According to Charles' law of ideal gas = volume is directaly propotional to temperature
gases will expand when temperature increase. mean The temperature of a gas is really a measure of the average kinetic energy of the particles. As the kinetic energy of the gas increases, the particles will move faster and want to make more collisions with the container or each other. However, remember that in order for the law to apply, the pressure must remain constant. The only way to do this is by increasing the volume.
according to kinetic theory of gas :-
Gases consist of particles in constant, random motion. They continue in a straight line until they collide with something - usually each other or the walls of their container.
Particles are point masses with no volume. The particles are so small compared to the space between them, that we do not consider their size in ideal gases.
No molecular forces are at work. This means that there is no attraction or repulsion between the particles.
Gas pressure is due to the molecules colliding with the walls of the container. All of these collisions are perfectly elastic.
