Which statement goes against the kinetic theory of gases?
a. the size of gas molecules is negligible compared to the volume of the container in which they are kept.
b. gas molecules possess mass and are in constant, random motion.
c. gas molecules will never collide with the walls of the container.
d. gas molecules interact only through elastic collisions.
e. the average kinetic energy of gas molecules is proportional to the kelvin temperature of the gas.

The correct option is C.

The kinetic theory of gases is a scientific law that explain the behavior of ideal gases. The law explains that, gas molecules usually fills the entire container in which they are placed and that their size is negligible compared to the volume of the container in which they are kept. The molecules of gases also move about randomly colliding with one another and with the wall of the container. The higher the temperature of the gas, the higher the rate of collision of the gas molecules with one another and with the wall of the container.

the answer is c. Gas molecules will never collide with the walls of the container
