Question

Root mean square velocity of a gas molecule is proportional
to
(a) m¹/² (b) m⁰ (c) m⁻¹/² (d) m

Answer 1

Answer:

The correct answer is a

Answer 2

Root mean square velocity of a gas molecule is proportional

to :

• Root mean square velocity formula is given below,

• μrms = (3RT/M)½

- μrms = root mean square velocity in m/sec

- R = ideal gas constant = 8.3145 (kg·m2/sec2)/K·mol

- T = absolute temperature in Kelvin

- M = mass of a mole of the gas in kilograms.

• From here, we get that

μrms is directly proportional to m⁻¹/²
