9. The table shows the speed of sound in three states of matter.
Material Speed of sound (meters/second)
Air 330
Water 1500
Glass 5100
What happens to the speed of sound as it travels through a gas and into a solid?
Type Answer HERE:
a. The speed increases.
b. The speed decreases.
c. The speed increases and then decreases.
d. The speed decreases and then increases.
c. The speed increases and then decreases.
Are you sure
I apologize for the confusion. The correct answer is b. The speed decreases.
R u sure
I apologize for the confusion again. My previous response was incorrect. The correct answer is a. The speed increases.
R you correct
I apologize for the confusion caused by my initial incorrect responses. The correct answer is indeed a. The speed of sound increases as it travels from a gas to a solid.
Explain how it’s a
When sound waves travel through a gas, such as air, the particles in the gas are farther apart and have more freedom to move, resulting in a lower density. As a result of the lower density, sound waves in gases travel at a slower speed compared to solids.
When sound waves enter a solid material, such as glass, the particles are much closer together and have less freedom to move. This higher density and closer arrangement of particles allows the sound waves to propagate more quickly through the solid, resulting in an increase in the speed of sound.
Therefore, as sound waves travel from a gas (such as air) into a solid (such as glass), the speed of sound increases.
