Question

Arrange the following materials for increasing speed of sound A. Sea water
B. Granite
C. Water
D. Hydrogen
E. Air Choose the correct answer from the options given below:

• A. E, D, C, A, B
• B. D, C, A, E, B
• C. C, A, D, E, B
• D. A, B, C, D, E

Hint:

Sound travels fastest in solids and slowest in gases.

Answer 1

The Correct Option is A

Concept:
Speed of sound depends on elasticity and density of medium.
Step 1:
Sound travels slowest in gases. Air has lower speed than hydrogen.
Step 2:
Sound travels faster in liquids than gases. Sea water has slightly greater speed than pure water.
Step 3:
Sound travels fastest in solids like granite.
Step 4:
\[ E<D<C<A<B \] \[ \boxed{\text{Correct Option = (1)}} \]
