2) Assertion: Sound travels faster in solids
than in gases.
Reason: Solid posses a greater density than
that of gases.​

Answer 1

Answer:

In solid atoms are tightly pack so that'swhy sound travel faster in them

Explanation:

Sound waves must require a medium for their propagation or travelling.Basically atoms are tightly hold together in solid and that act as a perfect medium for sound waves to pass through them while in liquids particles are slightly bounded to eachother and that doesn't act as the suitable medium for the sound waves to pass.
