Question

What's the speed of a sound wave through water at 25° Celsius? A. 750 m/s B. 1,500 m/s C. 1,250 m/s D. 1,000 m/s\

Answer 1

The correct answer option is B. 1,500 m/s.

Step-by-step explanation:

The speed of a sound waves in the water at 25° Celsius is approximately 1500 meters per second.

Sound is a kind of mechanical wave which needs a medium to propagate and does not travel through a vacuum. Sound travels at different speed in different media depending on different factors.

For instance, here in this the medium for the sound to travel is water and its temperature is one factor that will affect it.

Sound waves tend to travel faster at higher temperatures but for around 20 to 25 °C, their speed is 1500 m/s.

Answer 2

Sound travels at the average of 1500 meters per second at room temperature in water but in general, sound waves travel fastest in solids, then in liquids and slowest in gases. The molecules in solids are closest together, enabling energy of the sound waves to be transferred through vibrations faster than in liquids or gases. Also, sound travels faster on higher temperatures as the particles have more energy that they can vibrate faster than when it is cold.
