उत्तर
The Velocity of sound is high in gases than liquids - false.
Reason:
The velocity of a sound wave is maximum in solids because they are more elastic in nature than liquids and gases. Since gases are the least elastic in nature, the velocity of sound is the least in a gaseous medium.
So VS > VL > VG.
