Question

lncreasing the temperature four
times doubles the velocity of sound.
True
False​

Answer 1

$\huge\mathcal\blue\}answer$

pressure has a direct effect on the velocity of sound in a gas. The velocity of sound is equal to the root of ratio of pressure to the density of the gas. So if the pressure becomes four times, the velocity of sound becomes twice of the initial velocity. It remains constant at constant temperature.
