Questions
The molecules ofa given mass of a gas have a rms velocity of 200 m,/sec at pressure. When the temperature is , the rms velocity in m./sec will be
detailed solution
Correct option is C
Change in pressure will not affect the rms velocity of molecules. So we will calculate only the effect of temperafure.As vrms ∝ T∴ v3000v4000 = 300400 = 34 ⇒ 200v400 = 34⇒ v400 = 200 × 23 = 4003m/sSimilar Questions
The rms velocity of a gas at a certain temperature is times than that of the oxygen molecules at that temperature. The gas can be
