Lucas is boiling 200 g of salt water in an open pot on the stove. Which is a possible weight of the contents of the pot after 10 minutes of boiling?

• 150 g because some water evaporates into the air surrounding the pot and decreases the total mass

• 100 g because the salt dissolves in the hot water and has no mass

• 200 g because none of the salt or water is lost during the interaction and mass is conserved

• 250 g because some of the water evaporates into the air surrounding the pot, but the salt becomes a solid and adds mass
