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

If a gas, at constant temperature and pressure expands, then its

Doubling the pressure of a gas at constant temperature, doubles the volume occupied the gas.

In the process pV^2= constant, if temperature of gas is increased, then

The percentage change in the pressure of a gas at constant temperature is 200% (increases). Calcualte the percentage change in the volume of the gas.
