Answer:
The mass can not be neither created nor destroyed but transformed by chemical reactions or physical transformations in an isolated recipient.
Step-by-step explanation:
Hello,
In case, no matter the carried out experiment, the law of conservation of mass always leads the same: the mass can not be neither created nor destroyed but transformed by chemical reactions or physical transformations in an isolated recipient.
In such a way, we must consider that any system closed to every form of transport of matter, will show a no change in its mass as time goes by, since the system's mass cannot change neither by additions nor withdrawals. Therefore, the quantity of mass is conserved over time.
Best regards.
