The velocity of sound is largest in (c) steel rod.
- The velocity of sound depends on the density of the material it is travelling in and among the given options air, water, Steel rod and kerosene oil, the densest material is Steel rod.
- Sound travels through the collision of atoms or molecules of the medium it is travelling in and the denser the medium is the tightly the molecules are packed together which allows the sound to move faster.
- That's why when someone will try to scream in space nobody will be able to hear that sound because in space there are no molecules present.
- Speed of sound in steel rod at 25 degrees Celsius is approximately equal to 5000m/s

The velocity of sound is largest in steel rod.
The speed of sound depends just upon its temperature and construction. The speed has a weak dependence on repeat and pressure in regular air, veering off to some degree from ideal lead. The speed of sound insinuates the speed of the sound waves in the air. In any case, the speed of sound changes starting with one substance then onto the next.
