Which of the following is true for a heating curve? O A. It shows how the pressure of a substance changes when heated. OB. It shows how the temperature of a substance changes when heated. ОС. It shows how the volume of a substance changes when heated. OD It shows how the mass of a substance changes when heated.​

Changes to the amount of energy through thermal transfer is most appropriate to show changes in the to temperatures of the substances as there is an increase in the thermal energy in the closed system. The increase in molecular energy through the heating process is what happens when the energy is transferred from one compound to another.
