Question

Ratio of average to most probable velocity is

• A. 1.128
• B. 1.224
• C. 1.0
• D. 1.112

Answer 1

Answer: (A)

1.128

Answer 2

Average speed : most probable speed

$\sqrt { \frac { 8 R T } { \pi M } } : \sqrt { \frac { 2 R T } { M } }$ ⇒ $\sqrt { \frac { 8 } { \pi } } : \sqrt { 2 }$ ⇒ 1.128 : 1.
