Find out the ratio between the absolute temperature of two samples of hydrogen and oxygen gases, if their molecules rms speed are equal.

Text Solution

Verified by Experts

rms speed ,`c=sqrt((3RT)/M)`
For hydrogen molecular weight `M_1=2` and for oxygen , `M_2=32.`
`thereforec_1/c_2=sqrt(T_1/T_2.M_2/M_1)or,T_1/T_2=M_1/M_2.(c_1/c_2)^2=2/32.(1/1)^2=1/16`.
