In this short, Physics Bhau explains one of the MOST asked MCQs of JEE and NEET — straight from NCERT Class 11 Kinetic Theory chapter.
This exact question appeared in:
✔️ JEE-2021
✔️ NEET-2020
✔️ NEET-2021
NCERT Line से वही word-to-word पूछा गया है!
According to the Equipartition of Energy Theorem, any mono-atomic gas molecule has 3 translational degrees of freedom (x, y, z directions).
Each degree contributes ½ kBT energy.
Hence correct option: 3/2 kBT
This question is extremely important for JEE-NEET 2026, and must be memorized directly from NCERT.
Monoatomic Gas → 3 Degrees of Freedom
Only translational motion → no rotation, no vibration.
✔️ Correct Answer: B (3/2 kBT)
✔️ Direct NCERT line
✔️ 3 times repeated in national exams
