Question

3. Why is it important to perform an activity in a closed system to prove the law of conservation of
mass? Explain with examples.
​

Answer 1

Answer:

The law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as system's mass cannot change, so quantity cannot be added nor removed. Hence, the quantity of mass is conserved over time.
