The RMS velocity of nitrogen gas molecul...

The RMS velocity of nitrogen gas molecules is 'V cm/sec at a certain temperature. When the temperature is doubled, the molecules dissociated into individual atoms. Now the RMS velocity of nitrogen atoms is x V cm/sec. What is the value of 'x'?

Text Solution

Verified by Experts

The correct Answer is:
2
`(C_(N_2))/(C_N) = V/(C_N) = sqrt((T_1)/(28) xx 14/(2T_1)) implies C_N = 2V`
