Question

Find RMS speed, average speed and probable speed of
$co_2$gas at
27degrees Celsius
​

Answer 1

Answer:

We know that the root mean speed,

mu = sqrt(3RT / M)

where R = 8.314

T = 27 °C = 273+27= 300 k

M of Co₂ = 44 g/mole = 44/1000 kg / mole

=n0.044 kg/mole

Hence,

μ = √(3*8.314*300)/0.044

= 412.38 m/s

Hence the most probable speed of CO2 gas molecule at 27°C is 412.38 m/s
