1.	If the rms speed of hydrogen molecules at 300K is 1930ms^(-1). Then what is the rms speed of oxygen molecules at 1200K.
Answer» Solution :From RMS speed , `nu_(rms)=SQRT((3RT)/M)` `nu_(O_(2))=sqrt((3RT_(O_(2)))/M_(O_(2))),nu_(H_(2))=sqrt((3RT_(H_(2)))/M_(H_(2)))` `nu_(O_(2))/nu_(H_(2))=sqrt(T_(O_(2))/T_(H_(2)).M_(H_(2))/M_(o_(2)))` `nu_(O_(2))=sqrt((1200/300xx2/32))xx1930=1930/2` `nu_(O_(2))=965ms^(-5)`
