Suppose a gas sample in all have 6 × 10 23 molecules. Each 1/3 rd of the molecules have rms speed
10 4 cm/sec, 2 × 10 4 cm/sec and 3 × 10 4 cm/sec. Calculate the rms speed of gas molecules in sample.
Text Solution
Verified by ExpertsThe correct answer is:
2
(2.16 × 10 4 cm/sec.)
u rms = 
= 
∴ u rms = 
= 2.16 × 10 4 cm/sec
