Question

Does a closed system obey the law of conservation of matter? Write one or two sentences explaining your answer

Answer 1

Yes, a closed system obeys the law of conservation of matter. The law states that matter cannot be created not destroyed, only transferred. Meaning that in a closed system, this matter will be lost from one object but a different object will gain the same matter that was lost, therefore only transferring it. If it were an open system, the matter would be transferred outside the system and therefore you would loose matter on the system, but still, matter was not destroyed or created, it was only transferred from one thing to another.
