Question

Hydrogen gas is filled in two identical bottles A and B at the same temperature the mass of hydrogen in the two bottle is 12 gram and 48 gram respectively in which bottle will sound travel faster how many times as fast as the other

Answer 1

the bottle in which less mass of hydrogen is there that is in bottle A with 12g
the density will be less and in gases sound is inversely proportional to the square root of density
it will travel root of (48/12)=root of 4 that is 2times

Answer 2

In the bottle with 12gm of hydrogen mass
because in which case density is more sound
travel faster their and
density is inversely proportional to mass
