Hvad siger loven om bevarelse af masse?
Conservation of mass
Loven om bevarelse af masse eller princippet om massebevarelse siger, at for ethvert system, der er lukket for alle overførsler af stof og energi, skal systemets masse forblive konstant over tid, da systemets masse ikke kan ændres, så der kan hverken tilføjes eller fjernes mængde. Massemængden bevares derfor over tid.
Conservation of mass
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.
