periodic table\nwhat characteristics would you expect to find in an experiment that applies heat energy to a substance undergoing a phase change?\na. the constituent particles of the substance change.\nb. the temperature of the substance keeps increasing as energy is added.\nc. the temperature stops increasing as the structure of the substance changes.\nd. the intramolecular bonds of the substance break, leading to the formation of newer molecules.

Answer

Brief Explanations:

During a phase - change of a substance (like melting or boiling), the added heat energy is used to break the intermolecular forces rather than increasing the temperature. The constituent particles remain the same, and intramolecular bonds don't break to form new molecules. The temperature remains constant during the phase - change as the structure of the substance changes.

Answer:

C. The temperature stops increasing as the structure of the substance changes.
