Detailed explanation-1: -Hence, sound travels fastest in solids and slowest in gases.
Detailed explanation-2: -As a rule sound travels slowest through gases, faster through liquids, and fastest through solids.
Detailed explanation-3: -Answer: Because the molecules of matter in a gas are spaced far apart, sound moves slowest through a gas. Sound travels faster in liquids than in gases because molecules are packed more closely together. Sound travels fastest through solids.
Detailed explanation-4: -As solids are closely packed molecules, sound travels fastest in solids and molecules of the liquid are not packed that much tighter, and in gases, molecules are loosely bound. This is the reason in gases, the speed of sound is slowest.
Detailed explanation-5: -Sound waves travel slowest in some very loose unconsolidated sands on the banks of rivers. The velocity of sound waves in such sands is as low as 100 m/s. Sound waves travel in air at about 330 m/s and this value is temperature dependent.
