Q74 / 90 · JEE Main 2024 (31 Jan Shift 1) · Physics

The parameter that remains the same for molecules of all gases at a given temperature is :

Correct answer
A
kinetic energy
B
momentum
C
mass
D
speed

Solution

From the kinetic interpretation of temperature, we know, $K E = \frac{3}{2} k_{B} T$ . Clearly, it depends only on temperature.

Hence, the correct answer is option: 'A'.
