Assuming the temperatature to be constant, as we go up in the atmosphere, the velocity of sound

While going up in the atmosphere, how the velocity of sound changes ?

Air gets thinner as we go up in the atmosphere. Will the velocity of sound change?

The velocity of sound at 15°C and 380 mm pressure is 340 m/s. If the temperature remains constant and pressure is doubled, the velocity of sound will be

The velocity of sound in air at 20^(@)C is 340ms^(-1) . Keeping the temperature constant, what will be the velocity of sound in air when the pressure of the gas is doubled?

The velocity of sound in air at 20^(@)C is 340ms^(-1) . Keeping the temperature constant, what will be the velocity of sound in air when the pressure of the gas is doubled?

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

Assume that the temperature remains essentially constant in the upper parts of the atmosphere. The atmospheric pressure varies with height as. (the mean molecular weight of air is M, where P_(0)= atmospheric pressure at ground reference)

Assume that the temperature remains essentially constant in the upper part of the atmosphere. Obrain an epression for the variation in pressure in the upper atmosphere with height, the mean molecular weight of air is M.
