Ethanol

Aluminium

Oxygen

Hydrogen

- Speed of Sound in Different Media

- The speed of sound varies in different materials depending on their density and elasticity.

- Option 1: Ethanol

- Sound travels slower in liquids compared to solids due to less stiffness.

- Option 2: Aluminium

- Sound travels fastest in solids. Aluminium, being a metal, has high elasticity and low density compared to its stiffness.

- The answer is Aluminium, where the speed of sound is highest, approximately 5,000-6,000 m/s.

- Option 3: Oxygen

- Sound travels slower in gases compared to liquids and solids, around 330 m/s.

- Option 4: Hydrogen

- Despite being a gas, hydrogen is lighter, allowing sound to travel faster than in oxygen but still much slower than in solids.
