Question

four molecules of a gas have speeds 1 2 3 and 4 kilometre per second the value of The RMS speed of the gas molecule is??? plz reply as soon as possible!!!!​

Answer 1

Answer:

RMS - root mean square speed

First square all the speeds

We get, squares of speeds be

1, 4,9,16 km^2/s^2

Mean of the squares of speeds is

(1+4+9+16)/4 = 30/4 = 7.5 km^2/s^2

Root of the mean of the squares of the speeds is

√(7.5km^2/s^2) = 2.74km/s

Rms speed of the four molecules is

2.74km/s
