Halving the kelvin temperature of a substance will result in:
a. doubling in the molecular motion and collisions between particles and the walls of the container
b. the same molecular motion and collisions between particles and the walls of the container
c. halving the molecular motion and collisions between particles and the walls of the container
d. quadrupling the molecule motion and collisions between particles and the walls of the container

Option (c) is the correct answer.

Explanation:

Temperature of a substance is directly proportional to kinetic energy.

Mathematically,           K.E =

where                 T = temperature

                           k = boltzmann constant

Therefore, more is the temperature of a substance more will be the kinetic energy of molecules present in the substance. Hence, more will be the number of collisions between the molecules of the substance.

So, when we half the kelvin temperature then kinetic energy of molecules will also become half.

Thus, we can conclude that halving the Kelvin temperature of a substance will result in halving the molecular motion and collisions between particles and the walls of the container.

i'm pretty sure it is letter c.) car
