Answer: Double decomposition
Explanation:
Answer:
Mass of the water is equal to the mass of ice
Explanation:
When ice melts, the mass remains the same even though its volume decreases leading to a decrease in density of water.
The mass remains the same because according to the law of conservation of mass, mass can neither be created nor destroyed. Since mass is neither created nor destroyed in the process of melting, the mass of water must remain the same.
