Question

3. Answer in points. The factors on which the
velocity of sound wave
wave depende
gaseous medium
​

Answer 1

Answer:

temperature and composition

Explanation:

It depends strongly on temperature as well as the medium through which a sound wave is propagating. The speed of sound in an ideal gas depends only on its temperature and composition. The speed has a weak dependence on frequency and pressure in ordinary air, deviating slightly from ideal behavior.

Answer 2

The velocity of sound in a gaseous medium depends on the physical conditions the temperature, density of the gas and molecular weight.

$\sf\blue\bigstar$ Temperature (T): The velocity of sound is directly proportional to the square root of the temperature of the medium. This means that increasing the temperature four times doubles the velocity.

$\sf\blue\bigstar$ Density (p): The velocity of sound is inversely proportional to the square root of density. Thus, increasing the density four times, reduces the velocity to half it's value.

$\sf\blue\bigstar$ Molecular weight (M): The velocity sound is inversely proportional to the square root of molecular weight of the gas. Thus, increasing the molecular weight four times, reduces the velocity to half it's value.
