The RMS speed of hydrogen is sqrt7 times the RMS speed of nitrogen. Ifis the temperature of the gas. Then

Answer»

`T_(H_(2))=T_(N_(2))`
`T_(H_(2))gtT_(N_(2))`
`T_(H_(2))ltT_(N_(2))`
`T_(H_(2))=sqrt7T_(N_(2))`

Solution :`(C ) (u_(RMS)(H_(2)))/(u_(rms)(N_(2)))=SQRT7=[(T(H_(2))M(N_(2)))/(T(H_(2))M(N_(2)))]^(1//2)=sqrt7`
Hence,`(T(H_(2)))/(T(N_(2)))=7(M(H_(2)))/(M(N_(2)))=l((2)/(28))=(1)/(2)`
`T_(h_(2))ltT_(N_(2))`
