STANDARD Physics Root Mean Square Velocity MCQ Question
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?
1200 K
600 K
300 K
150 K
Correct Answer
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.
