Explanations:
• The speed of sound in a particular medium depends on temperature and moisture of that medium. • The speed of sound decreases when it passes from solid gaseous medium. • In any medium, if the temperature increases, the speed of sound also increases and vice versa. • For example, the speed of sound in air at 00C is 331 m s⁻ ¹. and at 250C it is 346 ms⁻ ¹.
