In which medium would sound move the fastest

Answers

Answer 1
Answer: Sound moves the fastest through a solid medium. Since the molecules within a solid are compactly or closely placed, so sound travels faster through it. It has already been experimentally proved that sound travels 17 times faster through a solid steel than through the air. This shows that sound can travel faster though a solid than through liquid or gas. Another way to prove that sound travels faster through solid is , if we place our ear in the railway line, then we can hear the sound of the train coming whereas the sound cannot be heard through the air.

Answers

Answer:

Atoms of every element are shown in a skeletal model of an organic molecule.

Explanation:

Skeletal model of an organic molecule consists of various skeletal atoms that are used in making up of the molecule. Various conventions of  hydrogen and  carbon  atoms are employed in it. The molecules bonding and certain representation of molecular geometry are shown in the structural formula.

Use of skeletal formula is ubiquitous in organic chemistry. Thus, in organic chemistry atoms of every element are shown in the skeletal model of an organic molecule
