yes 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. change wording

Answer 1

Yes, according to the law of conservation, mass cannot be created or destroyed but only transformed. Therefore, when 5 grams of water evaporates into gas, it simply changes form into 5 grams of water vapor. The mass of the liquid water is essentially transferred into the mass of the newly formed water vapor.
