Questions
At which temperature the speed of sound in Hydrogen will be same as that of speed of sound in Oxygen at 100oC
a
– 148oC
b
– 212.5oC
c
– 317.5oC
d
– 249.7oC
detailed solution
Correct option is D
Speed of sound in gases is v=γRTM⇒T∝M(Because v, γ-constant). Hence TH2TO2=MH2MO2⇒TH2(273+100)=232⇒TH2=23.2K=−249.7°CTalk to our academic expert!
