The rms speed of the molecules of a gas in a vessel is 400 ms–1 . If

1.	The rms speed of the molecules of a gas in a vessel is 400 ms–1 . If half of the gas leaks out at constant temperature, the rms speed of the remaining molecules will be(a) 800 ms-1(b) 400√2 ms-1(c) 400 ms–1 (d) 200 ms–1
Answer» Correct Option (c) 400 ms^–1 Explanation: Root mean square velocity does not depends upon the quantity of gas. For a given gas and at constant temperature it always remains same.
