Hello,
Your questions states:
During a change of state, the temperature of a substance _____?
In which you gave us some choices:
A. decreases if the arrangement of particles in the substance changes.
B. remains constant until the change of state is complete.
C. increases if the kinetic energy of the particles in the substance increases.
D. increases during melting and vaporization and decreases during freezing and condensation.
Your answer would be:
B. remains constant until the change of state is complete.
Your explanation/Reasoning:
It absorbs the energy, then after the phase changes it then increases the temperature all over again.
Have a nice day:)
Hope this helps!
