300 m/s.

Question 13

Sound travels through liquid at about?

Answer 13

1500 m/s.

Question 14

Sound travels through solid at about?

Answer 14

2500 m/s.

Question 15

Sound can travel faster through solids and liquids than it does through gases such as air is because?

Answer 15

Solids are conductors of sound.

Question 16

Faster sound. In hotter or
cooler? Why?

Answer 16

Hotter because heat, just like sound, is a form of kinetic energy. At higher
temperatures, particles have more energy (kinetic) and thus, vibrate faster. And when particles vibrate faster, there will be more
collisions per unit time.

Question 17

Is Speed of sound directly affected by the temperature of the medium?

Answer 17

Yes

Question 18
