Question

The ratio of root mean square speed, average speed and most probable speed is ______.

Options

• 3π : 8 : 2π

• π : 2π : 3

• 2π : 3π : 8

• π : 2π : 6

Answer 1

The ratio of root mean square speed, average speed and most probable speed is 3π : 8 : 2π.

Explanation:

V_rms : V_avg : V_mp ⇒ `sqrt((3"RT")/"M") : sqrt((8"RT")/(π"M")) : sqrt((2"RT")/"M")`
