At a constant temperature, pressure of a gas is made 4 times. How is velocity of sound in the medium affected ?

If the pressure of a gas at constant temperature is increased four times, the velocity of sound in the gas will _________

If pressure increases in a medium velocity of sound wave ____.

If the pressure of a gas is increased by a factor 2,then the velocity of sound in it will:

If temperature of a medium increases velocity of sound ____ .

When the temperature of an ideal gas is increased by 600 K, the velocity of sound in the gas becomes sqrt 3 times the initial velocity in it. The initial temperature of the gas is
