Which of the following does not follow the kinetic molecular theory?
a. gas molecules possess mass but have negligible volume.
b. gas molecules attract each other during collision, which affects the overall energy.
c. the average kinetic energy of gas molecules is unaffected by the mass of the molecules.
d. the average kinetic energy of gas molecules increases with increasing thermal energy (higher temperature).

Gas molecules attract each other during collision, which affects the overall energy.

Explanation:

According to kinetic molecular theory:

A. Gas molecules possess mass but have negligible volume.: the volume of gas molecules is considered to be negligible as compared to the vessel of the container. So the given statement is true.

B. Gas molecules attract each other during collision, which affects the overall energy: The given statement is false. The collisions between gas molecules were considered to be perfectly elastic.

C. The average kinetic energy of gas molecules is unaffected by the mass of the molecules: True. The average kinetic energy depends upon the temperature.

D. The average kinetic energy of gas molecules increases with increasing thermal energy (higher temperature): True, it is directly proportional to the temperature.

answer: the primary difference between a hypothesis and a theory is that b hypothesis is falsifiable, but a theory has been proven to be correct. theory is an explanation of something that is happening but hypothesis is a guess of something that can happen

explanation:

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
