Under similar conditions of temperature and pressure , two gases (x and y) of equal masses and taken such that x and y occupy volumes of 2 l and 50 l , respectively . When sound waves are passed through both the gases , in which gas does sound travel with a greater velocity ?

Explanation

(i) ` V prop (1)/(sqrtd)`
(ii) Use `V prop (1)/(sqrtd)` , where 'V' is the velocity of sound in gas and 'd' is the density of the gas .
Compare the densities of the given two gases with the help of the given data .
Then compare the velocity of sound in both the gases .
(iii) Gas 'x'
