Question

How is speed of sound in air affected by the change in (9 tempera
(ü) pressure, (ii) density and (w) humidity?​

Answer 1

THE ANS IS PRESSURE AND HUMIDITY

Heat is a form of kinetic energy, just like sound. So as molecules vibrate faster, and heat increases, sound can travel faster; however, the speed of sound can also be affected by humidity and air pressure.

Answer 2

Answer:

I) temperature = speed of sound increase with increase in temperature.

ii) pressure =speed of sound does not effect with pressure.

iii) density = speed of sound increase with decrease in density.

iv) humidity= as humidity increases speed of sound decreases .

hope it helps ☺️
