What happens to a gas when its temperature decreases?

a) gas becomes a plasma
b) molecules move more slowly
c) energy of the particles increases
d) atoms in the gas are destroyed

I believe the correct response is B. Molecules move more slowly.

Using the kinetic energy theory, the energy of the molecule is proportional to the temperature of the environment where it is residing. IN this case, as the temperature increases, the energy of the molecule also increases. This is applicable otherwise. The answer is B

Edit the post so i can see the letters for each answer, and increase the points required so i'd be able to answer it.
