- In the gaseous state, particles exhibit high kinetic energy due to their rapid random motion.
- This movement results in frequent collisions, contributing to the pressure exerted by gases.
- Therefore, both the Assertion and Reason are true, and the Reason provides a correct explanation for the Assertion.
- Hence, Option A is the correct answer.

Understanding the Assertion and Reason
The question revolves around the behavior of gas particles and their kinetic energy. Let’s break down the Assertion and Reason to understand why option 'A' is correct.
Assertion (A)
- Particles of matter in the gaseous state indeed possess high kinetic energy.
- This is due to the significant distances between gas particles, allowing them to move freely and rapidly in all directions.
Reason (R)
- The random movement of particles in gases leads to frequent collisions.
- This characteristic of gas particles colliding with one another is a direct result of their high kinetic energy, which facilitates such movement.
Relationship Between A and R
- High kinetic energy in gas particles results in random motion, which in turn causes frequent collisions.
- Thus, the reason provided explains why the assertion is true.
Conclusion
- Since both the Assertion and Reason are true, and the Reason correctly explains the Assertion, the correct answer is option 'A'.
- This relationship highlights fundamental concepts in kinetic molecular theory, which describes the behavior of gases effectively.
In summary, the kinetic energy of gas particles is a primary factor in their movement and interactions, making both the Assertion and Reason valid and interrelated.
