Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Sound travels with a different speed in media. In what order does the velocity of sound increase in these media?

A	Iron, air and water
B	Air, water and iron
C	Iron, water and air
D	Water, iron and air

Explanation:

Detailed explanation-1: -Hence, increasing order of velocity of sound in the following media is as follows : Air, water and iron.

Detailed explanation-2: -Sound travels faster in liquids than in gases, and faster in solids than in liquids. So, the correct order of the speed will be: Vacuum < Gas < Liquid < Solid.

Detailed explanation-3: -Thus air, water, iron, is the correct increasing order .

Detailed explanation-4: -The speed of sound is 343.2 metres per second.

Detailed explanation-5: -The speed of the sound depends on the density and the elasticity of the medium through which it travels. In general, sound travels faster in liquids than in gases and quicker in solids than in liquids. The greater the elasticity and the lower the density, the faster sound travels in a medium.
