A) ? 148oC
B) ? 212.5oC
C) ? 317.5oC
D) ? 249.7oC
Correct Answer: D
Solution :
Speed of sound in gases is \[v=\sqrt{\frac{\gamma RT}{M}}\]Þ \[T\propto M\] (Because v, g-constant). Hence \[\frac{{{T}_{{{H}_{2}}}}}{{{T}_{{{O}_{2}}}}}=\frac{{{M}_{{{H}_{2}}}}}{{{M}_{{{O}_{2}}}}}\] Þ \[\frac{{{T}_{{{H}_{2}}}}}{(273+100)}=\frac{2}{32}\]Þ \[{{T}_{{{H}_{2}}}}=23.2K=-249.7{}^\circ C\]You need to login to perform this action.
