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.

Answer:
speed was the sport utility vehicle traveling is 14.08 m/s
Explanation:
Given data
car mass m1 = 1100 kg
speed s = 32 m/s
vehicle mass m2 = 2500 kg
to find out
speed was the sport utility vehicle traveling
solution
we will apply here conservation of momentum law
the momentum change of car is equal and opposite of the momentum change of vehicle
so equation are
m1 v1 - m2 v2 = 0
so here v2 will be
v2 = (m1 / m2 ) v1
put here all these value we get
v2 = (1100 / 2500 ) 32
v2 = 14.08 m/s
so speed was the sport utility vehicle traveling is 14.08 m/s
