during a Phase Change what is taking place for the temperature and the heat energy?

Question

a
The temperature and heat energy remain the same.
b
The temperature increases, but heat energy remains the same.
c
The temperature and heat energy are increasing.
d
The temperature remains the same, but heat energy continues to increase.

Answer 1

During a phase change, the temperature of a substance remains constant while heat energy is added or removed. This heat energy is used to break or form intermolecular bonds, rather than increasing the temperature.

Therefore, the correct answer is:

d. The temperature remains the same, but heat energy continues to increase.
