Is the speed of sound more in water or in steel?

उत्तर
Sound travels faster in steel than in water. In solids, the distances between the molecules are closer and thus the atoms are more densely packed than in liquids. Therefore, the molecules quickly collide with one another and transfer the vibrational energy.
