STANDARD Physics Root Mean Square Velocity MCQ Question

Type: MCQ-numerical-Medium-Class 11

0.014 kg of nitrogen is enclosed in a vessel at a temperature of 27°C. At which temperature the rms velocity of nitrogen gas is twice its the rms velocity at 27°C?

A

1200 K

B

600 K

C

300 K

D

150 K

Correct Answer

Option A

Detailed Explanation

Using the formula v_rms = √(3RT/M), and knowing that (v_rms)_2 = 2(v_rms)_1, we find T_2 = 300 x 4 = 1200 K.
