Question

at a certain temperature the rms velocity for O2 is 400 m/sec . at the same temperature the RMS velocity for H2 molecules will be
1) 100m/sec
2)25m/sec
3)1600m/sec
4) 6400m/sec
​

Answer 1

Answer:

3rd option

Explanation:

v1÷v2=square root of 3RT÷M

v1÷v2=square root of T1÷T2×M2÷M1

400÷v1= square root of T÷T×1÷16

v1=400×4=1600m/sec. HOPE IT WILL HELP YOU. MARK IT AS THE BRAINLIEST ANSWER
