plzzzz help

Answer 1

$\huge{\underline{\underline{\tt{\pink{Answer}}}}}\:$

Sound travels fastest through the medium of solids .

$\huge{\underline{\underline{\tt{\purple{Reasoning}}}}}\:$

• The speed of sound depends upon the properties of the medium through which it is travelling

• When we look at the properties of gas we can observe that molecules in gas only collide while condensation and rarefactions of sound move about .

• So the speed of sound has the same order of magnitude as the average molecular speed between the collisions

• Sound travels faster in liquids as compared to gases as the particles are more tightly packed .

• Sound travels the fastest in solids .

• In solids particles are packed very closely to each other as they have density .

• The closer the molecules , the tighter their bonds , the less time it take to reach to other molecules .

• It is easier for sound waves to go through solids rather than liquids and gases .

• Density is the mass of substance per volume .

Answer 2

Solid... Trust me...
