Question

Speed of sound in air :

(a)increase with pressure

(b)is independent of temperature

(c)increase with increase in humidity

(d)decrease with increase in humidity​

Answer 1

Answer:

(c) increases with increase in humidity

Explanation:

p =d RT/M

where d= density , T = temperature , R = universal constant , M = molar mass and p = pressure

where p is directly proportional to d

v= √ {YP/d}

put P=dRT/M

velocity of sound =√ {dRT/M}

Thus, the velocity of sound is directly proportional to square root of temperature . Thus if humidity increases , then the density decreases ,hence the speed of sound increases. Therefore if humidity increases velocity of sound also increases.
