Question

Kinetic energy of a gas molecule depends on :

• A. Volume
• B. Temperature
• C. Pressure
• D. None of these

Answer 1

The correct option is B Temperature

According to law of equipartion of energy among molecules of a gas $\frac{1}{2}KT$ energy is distributed foe each degree of freedom $\left(f\right).$

For instance $=K.E$ of translation motion of a gas molecule with $f=3$

$\Rightarrow K.E=\frac{3}{2}KT$ thus $K.E\propto T.$

Hence, the answer is temperature.
