Changes of State

Question 7 • GA-GSE Physical Science A

What happens if atoms lose energy during a change of state?

Answer
A
The atoms are pushed apart by repulsive forces and become less organized.
B
The atoms are pulled together by attractive forces and become less organized.
C
The atoms are pushed apart by repulsive forces and become more organized.
D
The atoms are pulled together by attractive forces and become more organized.

Explanation

When atoms lose energy, they move less and are less able to overcome the attractive forces between them. They move closer together and arrange themselves in a more orderly way as the substance changes to a more condensed state. Therefore, the atoms are pulled together by attractive forces and become more organized.
