Question

In the kinetic molecular theory:
(Correct answer +1, wrong answer -0.25)

• A. The gas molecules are considered as point source or masses i.e., they have no volume
• B. The gas pressure is dependent upon the molecular weight of the gas
• C. The kinetic energy of the gas dependent upon the nature of molecular weight of the gas
• D. All of the above

Answer 1

The correct option is A The gas molecules are considered as point source or masses i.e., they have no volume

A) Molecules are considered as point masses, because point masses do not have volume. Hence, volume of the molecule is negligible as compared to the volume of the container.

B) The pressure of the gas does not depend on the molecular weight of the gas.

C) Kinetic energy of the gas depends upon temperature and not on the nature of the gas.
