The correct answer is: **All physical and chemical changes, including changes that involve gases.**
The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction, meaning that the total mass of the reactants equals the total mass of the products, regardless of whether the changes are physical or chemical.
