Question
What is the effect of temperature and pressure on the speed of sound in a gas?
Advertisements
Solution
With an increase in temperature of the gas, there is increase in the speed of gas because an increase in temperature decreases the density of a gas. And the speed of sound is inversely proportional to the density of the gas. The speed of the gas is independent of the pressure of the gas.
