Kinetic Theory of Gases: Practice Problem & Solution

Solution Explained:

To solve this problem, we apply the core principles of Kinetic Theory of Gases. Understanding the underlying formula is key to arriving at the correct answer below:

Concept: Absolute zero and molecular energy. At absolute zero 0 K, the average kinetic energy of molecules is at its minimum (or zero for an ideal gas classically). However, molecules can still possess potential energy due to intermolecular forces or external fields. Hence, total energy is not necessarily zero. Both (A) and (R) are true, and (R) correctly explains (A).
