A system has both thermal energy and chemical potential energy. According to the law of conservation of energy, which statement describes the total
energy of this system?
A. It will decrease as thermal energy is transferred out of the system.
B. It will decrease over time as chemical potential energy is
transformed into thermal energy.
C. It will increase as thermal energy is created from chemical
potential energy.
D. It will remain constant because the total amount of thermal energy
plus chemical potential energy stays the same.
