Effect of density |
The velocity of sound in a gas is inversely proportional to the square of the density of the gas Velocity decreases wt density of the gases decreases |
Proportionality Decreases |
|
|
Effect of temperature |
Velocity at temperature 👆🏻
The velocity of sound in a gas is directly proportional to the square root of its temperature 🌡️ Vo ~ velocity of sound in gas at 0°C = 331ms-1
When the temperature changes by 1°C the velocity of the sound changes by 0.61 ms-1
|
Proportionality Increases Equation Change in the temperature |
|
|
Effect of relative humidity |
When humidity increases the speed of the sound increases We can hear sound from long distance is clearly during rainy seasons |
Increases clear sound |
