Question

which statement correctly compares the speed of sound in solids and gases? (1 point) the speed of sound is generally faster in solids than in gases, because solids are denser than gases. the speed of sound is generally faster in solids than in gases, because solids are less dense than gases. the speed of sound is generally slower in solids than in gases, because solids are denser than gases. the speed of sound is generally slower in solids than in gases, because solids are less dense than gases.

Explanation:

To solve this, we recall the physics principle: Sound travels faster in denser mediums. Solids are denser than gases. So the speed of sound should be faster in solids than in gases because solids are denser. Now we check the options:

• First option: States sound is faster in solids (correct) and reason (solids denser than gases, correct).
• Second option: Reason (solids less dense) is wrong.
• Third option: Speed comparison (slower in solids) is wrong.
• Fourth option: Both speed comparison and reason are wrong.

Answer:

The speed of sound is generally faster in solids than in gases, because solids are denser than gases.
