Question

38. root mean square velocity of a particle is v at pressure P. If pressure is increased two
times, then the r.m.s. velocity becomes
a) 2 V GRb) 3 V c) 0.5 V IT d) v

Answer 1

Answer: (D) v

Explanation:

Given that Vr.m.s of the particle at pressure p = v

Vr.m.s = $\sqrt{3RT/M}$

Root mean square of velocity doesn't depend on pressure

And thus it will remain the same

Therefore, your answer is (D) v
