Answer 1

Answer:

mass and volume will not change

Answer 2

Option C : Mass remains the same in a Compression and Rarefaction medium. Rest other physical quantities increase or decrease accordingly.

Compression :

• It is the region where the particles in the longitudinal wave are placed very close to each other
• As the particles are very closely packed, the volume of the sound wave is very less and compact
• With mass remaining the same and volume decreasing, the density increases according to the relation d = m/v.

Rarefaction :

• It is the region where the particles in the longitudinal wave are placed very far apart from each other
• As the particles are very loosely and lightly packed, the volume of the sound wave is very huge, spread, and diverse.
• With mass remaining the same and volume increasing, the density decreases according to the density relation.

Thus, as we move from compression to a rarefaction medium with a longitudinal wave :

1. The pressure decreases ( Compression has high pressure )
2. Density decreases ( Compression is denser)
3. Mass remains the same
4. Volume increases ( Compression is more compact )
