what are the four factors that affect the speed of sound in gas medium?
Answers
Answer:
Factors affecting speed of sound in gas, such as: Pressure, Density, Temperature, Humidity, frequency etc.
Answer: Elasticity of medium, density, temperature and Humidity.
Explanation:
Elasticity of medium:- The particles return to original position quicker which means it's ready to move again faster which causes it to vibrate at higher speeds. Speed of sound in gas increases with elasticity of the medium.
Density:- When a medium is dense, the particles are larger. It takes more time to vibrate larger particles.. Speed of sound in gas decreases when density is more.
Temperature:- Molecules at higher temperature has more energy and allows sound waves to travel faster. Speed of sound in gas increases with temperature.
Humidity:- The more humid the air is, the less dense it is.. The less denser, the more the speed of sound in gas...Speed of sound in gas increases with humidity.
[Note: The other answer mentions pressure and frequency but air pressure has no effects on speed of sound in gas and speed of sound is nearly independent of its frequency]
