Calculate the RMS velocity of molecules of a gas of which the ratio of two specific heats is 1.42 and velocity of sound in the gas is 500 m/s.A. 727 m/sB. 527 m/sC. 927 m/sD. 750 m/s |
Answer» Correct Answer - A `V_(S)=sqrt((gamma)/(3))C_(rms)` `=sqrt((1.42)/(3))xxC_(rms)` `500=sqrt(0.47)C_(rms)` `C_(rms)=(500)/(sqrt(0.47))=727m//s`. |
