6. Define dynamic equillibrium

  • The inputs are not level to the outputs in the system.
  • When the system is not in a state of balance.
  • The state of balance in a system, where both the level of inputs and outputs are equal.
  • The level of inputs and outputs are not equal.

7. What is an isolated system?

  • A system that transfers both energy and material.
  • They have no interaction with anything outside of the interaction boundary. No input of energy or matter.
  • A system that is closed.
  • A system that has interactions outside of the system boundary.

8. What is a closed system?

  • A system that transfers only matter into and beyond the system boundary.
  • A system that transfers energy into and outside of the system boundary, does NOT transfer matter.
  • A system that transfers both energy and matter into and beyond the system boundary.
  • A system that has interactions only outside of the system boundary.

9. identify one incorrect charcteristic of systems

  • Systems accuratley show the reality of what is happening in systems.
  • Systems are a generalisation of reality- give an idea of what is happening in a system, but the reality is more detailed.
  • Only SOME systems exchange energy/matter beyond their defined boundary.
  • Different parts of the system are connected and intergrated together.
