WebAug 9, 2024 · 6.2.1.2: Substances can undergo physical changes which do not change the composition or the total mass of the substance in a closed system. Benchmarks: - Describe how mass is conserved during a physical change in a closed system. - Identify evidence of physical changes, including changing phase or shape, and dissolving in other materials. WebSep 20, 2024 · Why does mass not change in a chemical reaction? During a chemical reaction, atoms are neither created nor destroyed. The atoms of the reactants are just rearranged to form products. Hence, there is no change in mass in a chemical reaction. Does mass change with heat? The mass remains the same. The volume increases. …
