Leigh is preparing popcorn for her friends. She removes a stick of butter from the refrigerator and cuts a fourth of it from the rest. Leigh remembers her lesson in school today about the conservation of mass that occurs during state changes. She wants to test what she learned, so she measures the mass of the butter she will melt.
