all the above


​

Answer 1

Answer:

I think all of the above

Answer 2

Answer:

answer is

Explanation:

Air pressure has no effect at all in an ideal gas approximation. This is because pressure and density both contribute to sound velocity equally, and in an ideal gas the two effects cancel out, leaving only the effect of temperature. Sound usually travels more slowly with greater altitude, due to reduced temperature
