the speed of sound in gas-with increase of humidity
a)increases b)decrease c)no change d)none of these
Answers
Answer:
a) increase
Explanation:
As the density of moist air is less than that of dry air, the speed of sound in moist air is greater than the speed of sound in dry air, for the same pressure. This implies that as humidity increases, the speed of sound in air increases.
Answer:
a)Increases
Explanation:
To understand this you must understand what sound is. Sound is a wave.
a wave is a disturbance that moves energy from one place to another it is made of particles so if no particles no wave, that's why we can't hear in space because sound wave can't travel.
Now let's come to the question, if the humidity is more the density of the air is more which mans more particles in the air so the sound wave will travel more fast with more particles in the air.
Hope this helps you understand the concept.
