Chapter 12, Problem 2STP

Interpretation Introduction

Interpretation:

The option that is not an assumption of kinetic theory of gas must be chosen from the given options.

Concept introduction:

Kinetic theory of gas considers the motion of gas molecules due to temperature. Gas molecules show Brownian motion and they collide with each other along with the wall of the container.

Answer to Problem 2STP

Correct answer: Option B is correct.

Explanation of Solution

Reason for correct option: Option B is correct because all the gas particles in a sample have different velocities.

Conclusion

Reasons for incorrect options: Option A is incorrect as it is not a wrong statement regarding kinetic theory of gas. It correctly stated that the collisions between gas particles are elastic.

Option C is incorrect as it is not a wrong statement regarding kinetic theory of gas. It correctly stated that a gas particle is not significant attracted or repelled by other gas particles.

Option D is incorrect as it is not a wrong statement regarding kinetic theory of gas. It correctly stated that average kinetic energy of all gases at a particular temperature will be the same.
