Question

The respective speeds of five molecule aee 2,1.5,1.6,1.2 km/s the most probable speed in km/s will be ?

Answer 1

Hello Dear,

◆ Answer -

vmp = 1.306 km/s

◆ Explanation -

RMS velocity of gas molecules is calculated by -

vrms = √[(2²+1.5²+1.6²+1.6²+1.2²)/5]

vrms = √(12.8/5)

vrms = 1.6 m/s

Most probable speed is calculated by -

vmp = √(2/3) × vrms

vmp = 0.816 × 1.6

vmp = 1.306 km/s

Therefore, most probable speed of gas is 1.306 km/s.

Thanks dear...
