• B. Diamond
• C. Steel
• D. Iron

Answer 1

Answer:

B. Diamond

Read Explanation:

Speed of sound:

• The speed of sound varies from substance to substance.

• Typically, sound travels most slowly in gases, faster in liquids, and fastest in solids.

• Sound travels fastest in solids because the molecules are tightly packed together, allowing sound waves to move faster

• In exceptionally stiff materials such as diamond, sound travels at 12,000 m/s.

• The speed of sound in steel is 6,000 meters per second.

Speed of sound in

• Air : 340 m/s

• Water : 1,480 m/s

• Mercury : 1452 m/s

• Glass : 5000 m/s

• Aluminium : 5000 m/s

• Iron : 5000 m/s
