The molecules of a given mass of a gas have rms velocity of 200 ms−1 at 27°C and 1.0 × 105 Nm−2 pressure. When the temperature and pressure of gas are respectively, 127°C and 0.05 × 105 Nm−2 the rms velocity of its molecules in ms−1 is:
- \(\frac{400}{\sqrt{3}} \mathrm{~ms}^{-1}\)
- \(\frac{800}{\sqrt{3}} m s^{-1}\)
- \(\frac{300}{\sqrt{3}} m s^{-1}\)
- \(\frac{500}{\sqrt{3}} m s^{-1}\)
Answer
(B) 800 3 m s^ -1
