If atoms [Blank] energy during a change of state, they are pulled together by attractive forces and become more organized.

If atoms lose , they become more organized.
When energy is removed from a given amount of atoms, they enter a more organized state because their attractive forces overcome their repulsive forces, which causes them to come closer. This is observed when a gas is condensed to a liquid, and then also when a liquid freezes into a solid. This moving closer also limits the motion of the particles.

Answer:

1. 5 m/s

2. 8 m/s

3. 10 s

4. 3 m/s

Explanation:

1. Average speed = distance / time

s = 20 m / 4 s

s = 5 m/s

2. First, find the time to travel from A to B:

60 m = 10 m/s × t

t = 6 s

Now find the average speed from A to C:

s = 80 m / (6 s + 4 s)

s = 8 m/s

3. If t is the time traveling from C back to B, and the average speed of the whole trip is 5 m/s, then:

5 m/s = 100 m / (6 s + 4 s + t)

t = 10 s

4. Average velocity = displacement / time

v = 60 m / 20 s

v = 3 m/s
