Answer 1

3) The amount of matter within the system remains the same

5) The cycle has a well-defined starting and stopping point.

Step-by-step explanation:

A closed system is a system that the boundaries of a system cannot be passed by either matter or energy.

Hence, generalisations can be made based on a closed system and the law of conservation of mass which states that matter can neither be created nor destroyed but can only change form.
