Answer

Brief Explanations:

According to the law of conservation of energy, in an isolated system (a system that does not interact with its surroundings), the total energy is conserved (remains constant). When a system interacts with its surroundings, energy can be transferred in the form of work or heat, so the total energy of the system can change.

Answer:

  • If a system interacts with its surroundings, the system's total energy can change.
  • If a system does not interact with its surroundings, the system's total energy remains constant.
