Conservation of Mass... If an ice cube is placed in a zip lock bag and has a mass of 28g and is left to melt due to an increase in thermal energy. What will be the mass of the liquid in the zip lock bag after the complete change of state has occurred?
29 g, water has more mass than a solid ice cube
27 g, water has less mass than a solid ice cube
28 g, water has the exact same mass as the solid ice cube before and after the change of state
