Apply the law of conservation of mass to explain how mass is conserved when water evaporates.
Answer (2)
The law of conservation holds that mass can not be destroyed but can only take on different forms. So if 5 g of water becomes a gas it becomes 5 g of water vapor. The mass of the liquid water is simply transferred into the mass of the newly formed water vapor.
The law of conservation of mass states that mass cannot be created or destroyed. During evaporation, water changes from liquid to vapor, but the total mass remains the same. In a closed system, the mass is conserved as vapor can condense back into liquid, ensuring total mass consistency.
