Question

D. Paul says: "The table shows that sound travels faster in metal than in other solids."
(i)Explain why this is not a good condusion to draw from the data in the table
(ii) How could you find out if sound does travel faster in metals than in other solids?​

Answer 1

Answer:

here it is mate

Explanation:

(i) it's definitely not a good conclusion to draw data from the table because in the table the speed of sound in water and air are given at different temperatures.

speed of sound in air is given at 20 degree celcius and speed of sound in water is given at 10 degree celcius while all others are given at ordinary temperatures(room tempertaure)which shows that its not a good conclusion as different mediums are given at different temperatures th ures

(ii) the sound waves need a medium to travel.it travels by vibrating the molecules present inside a medium.in a metal such molecules are more tightly packed than any other solids.hence,sound moves faster in metals than in other solids.
