The air that was inside the balloon will expand to fill the room
Explanation:
Matter exists in three states:
- Solid: in a solid, the molecules are bound to each other by strong intermolecular bonds, so they are not able to move freely, but only to vibrate around their fixed position. As a result, solids have a definite shape and a definite volume.
- Liquid: in a liquid, the molecules are free to slide past each other, however there are still intermolecular forces acting between them that prevent them to move too far apart from each other. As a result, liquids have a definite volume, but not a definite shape.
- Gas: in a gas, intermolecular forces between molecules are negligible, and molecules can move freely. As a result, gases have no definite volume and no definite shape.
According to the definition of gas, this means that in this problem, when the air is released from the balloon, the molecules of air will move out of it and will try to fill the whole space available, which is the room.

reflection of sound waves from a surface back to the initial listener
Answer:
57.5022228905 s
Explanation:
= Initial voltage
= Final voltage = 0.401 V
= Initial time = 8.36 s
= Final time
K = Kinetic Energy =
C = Charge =
Voltage is given by
We have the relation
The time taken is 57.5022228905 s
