Question

d. Hydrogen gas is filled in two
identical bottles, A and B, at the
same temperature. The mass of
hydrogen in the two bottles is 12
gm and 48 gm respectively. In
which bottle will sound travel
faster? How may times as fast as
the other?​

Answer 1

Answer:

Mass of hydrogen in bottle A= w

1

=12g

Mass of hydrogen in bottle B= w

2

=48g

∵ Density ∝ Mass

ρ

ρ

=

w

w

and for velocity V∝

ρ

1

∝

w

1

∴V

/V

=

ρ

/ρ

=

w

48

=

Hence sound will travel faster in bottle A and speed will be twice as that of bottle B.
