Question

In an open system, _______ can get into or out of the system.

  1. Heat
  2. Matter
  3. Both a and b
  4. Neither a nor b

hintHint:

open system examples are steam turbines and stove top.

The correct answer is: Both a and b


    In an open system, both heat and matter can get into or out of the system.

    In an open system, both mass and energy (heat and matter) can be transmitted. An open system can exchange both matter and energy that is present with its surroundings. The matter is easily exchanged between the open system and its surroundings. This can be simply described by adding or subtracting matter.
