MCQ
In case of hydrogen and oxygen at $N.T.P.$, which of the following quantities is $/$ are the same?
- Aaverage momentum per molecule
- Baverage kinetic energy per molecule
- Ckinetic energy per unit volume
- ✓All of the above
✓
Answer
Correct option: D.
All of the above
d
The average kinetic energy is given as, $K=\frac{3 R T}{2 V_{A}}$
The average kinetic energy is given as, $K=\frac{3 R T}{2 V_{A}}$
So, the kinetic energy is proportional to the temperature.
The per unit mass of molecule will change So, the volume and momentum will also be changed.
Thus, in case of hydrogen and oxygen at NTP the average kinetic energy per molecule will be same.
