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 over time as chemical potential energy is
transformed into thermal energy
O B. It will increase as thermal energy is created from chemical
potential energy
C. It will remain constant because the total amount of thermal
energy plus chemical potential energy stays the same.
D. It will decrease as thermal energy is transferred out of the system.
