Question

Decide which of the following statements are true and which are false, concerning the kinetic molecular theory.

True False  The particles are so small compared with the distances between them that the volume of the individual particles can be assumed to be zero.

True False  The molecules in a real gas have finite volumes and do exert forces on each other, thus real gases do not conform to some of the assumptions of an ideal gas as stated by the kinetic molecular theory.

True False  The particles are in constant motion. The collisions of the particles with the walls of the container are the cause of the pressure exerted by the gas.

True False  The average kinetic energy of a collection of gas particles is assumed to be directly proportional to the Kelvin temperature of the gas.

True False  The particles are assumed to exert no forces on each other; they are assumed neither to attract nor to repel each other.

Answer 1
