Which two generalizations can be made based on what you know about cycles of matter in a closed system?
1 New matter is added, and old matter is destroyed.
2 Matter changes its physical form, allowing it to return to its original state.
3 The amount of matter within the system remains the same.
4 Matter and energy can cross the boundaries of the system.
5 The cycle has a well-defined starting and stopping point.

Respuesta :

Answer: The correct answer is option 3) The amount of matter within the system remains the same and 5) The cycle has a well-defined starting and stopping point.

A closed system can be defined as a system in which there is the only exchange of energy with the surrounding, while no exchange of matter takes place.  

In a closed system, the cycle has a well-defined starting and stopping point.

Therefore, the two generalizations which can be made for cycles of matter in a closed system are option 1) and 5)

Answer:

The statements 3 and 5 can be two generalization made by the information of a closed system.

Explanation:

  • A closed system is system in which neither matter nor energy cannot cross the boundaries of the system.
  • So the statement 3 which is the amount of matter remains same in the system is correct one on the bases of the law of conservation of mass.
  • This law states that neither mass and energy can be created nor destroyed but they can change from one form to another form.
  • In the given system, reaction of matter is in cyclic form, the starting and stopping points of reaction can be well defined on the basis of reaction.
