-The phase changes B → C and D → E are not associated with temperature increases because the heat energy is used up to ________.
A)increase distances between molecules
B)break intramolecular bonds
C)rearrange atoms within molecules
D)increase the velocity of molecules

Question

-The phase changes B → C and D → E are not associated with temperature increases because the heat energy is used up to ________.
A)increase distances between molecules 
B)break intramolecular bonds 
C)rearrange atoms within molecules 
D)increase the velocity of molecules 
E)increase the density of the sample

Quizplus · Accepted Answer

During phase changes, such as melting or boiling, heat energy is used to overcome intermolecular forces and increase the distance between molecules, rather than increasing temperature.
