Questions
Oxygen is 16 times heavier than hydrogen. Equal volumes of hydrogen and oxygen are mixed. The ratio of speed of sound in the mixture to that in hydrogen is
detailed solution
Correct option is A
Density of mixture =ρmix=VO2ρO2+VH2ρH2VO2+VH2=VρO2+ρH22 V=ρO2+ρH22 since VO2=VH2=V=ρH2+16ρH22=8.5ρH2⇒v∝1ρ⇒VmixVH2=ρH2ρmix=ρH28.5ρH2≈18Talk to our academic expert!
