Question

1 makena measured the mass of a closed beaker containing several ice cubes. the mass was 125 g. an hour and a half later, makena returned to find that the ice had melted. what type of change occurred and what would the measured mass be now? a physical change, 115 g b chemical change, 125 g c physical change, 125 g d chemical change, 115 g

Explanation:

Melting of ice is a physical change as it only changes the state of water from solid to liquid without altering its chemical composition. According to the law of conservation of mass in a closed - system, the mass remains the same. Initially, the mass was 125g, so it will still be 125g after melting.

Answer:

C. Physical change, 125 g
