Question

What would happen to the speed of sound travelling through water as it freezes and becomes solid? A) The speed of sound should increase as it solidifies. B) The speed of sound should decrease as it solidifies. C) The speed of sound does not change because the chemical is still H2O. D) The speed of sound only changes with temperature. Ice freezes at a constant temperature.

Answer 1

Answer: The correct answer is option(A).

Step-by-step explanation:

Sound travels fast in air , faster in liquid and fastest in solids.

This is because the particles in solid state are tightly packed by which no collisions between particles are present unlike in liquids and gases.

In gases, particles are far apart due to which particles are free to collide which each other. Due to these collisions the speed of sounds slows down in the gaseous state.

According to question the speed of the sound in water will increase on freezing because state of water is changing into solid state from liquid state. And sounds travels fastest is solid state of matter which means that speed will increase on solidification.

Hence, correct answer is option A.

Answer 2

The speed of sound travels fastest in solid, faster in liquid, and slowest in air.\

So

A) The speed of sound should increase as it solidifies.


should be your answer
