અહી \({{\text{T}}_{\text{H}}}{\text{  =  27 }}{{\text{ }}^ \circ }{\text{C  =  300 K,}}\,\,{{\text{M}}_{{{\text{O}}_{\text{2}}}}}\, = 32\,g\,mo{l^{ - 1}}\,,\,\,{M_{{H_2}}} = 2\,g\,mo{l^{ - 1}}\)

હવે \(\frac{1}{2}{M_O}\,\, < {\upsilon ^2} > \, = \,\frac{3}{2}RT\,\,\,\)

\(\therefore \,\,\,{\upsilon _{rms}} \propto \sqrt {\frac{T}{{{M_O}}}} \) પરથી \(\sqrt {\frac{{{T_O}}}{{{M_{{O_2}}}}}} \)

\( = \,\,\sqrt {\frac{{{T_H}}}{{{M_{{H_2}}}}}} \,\,\therefore \,\frac{{{T_O}}}{{{M_{{O_2}}}}} = \frac{{{T_H}}}{{{M_{{H_2}}}}}\,\,\,\,\therefore \,\,\,{T_O} = \frac{{{M_{{O_2}}}}}{{{M_{{H_2}}}}} \times {T_H}\,\, = \frac{{32 \times 300}}{2}\,\,\,\, = 4800\,K\)
