Final answer:
Both heating sugar and melting ice follow the law of conservation of mass because the total mass remains unchanged during these processes in a closed system.
Step-by-step explanation:
The question asks whether heating sugar and melting ice follow the law of conservation of mass. The correct answer is A) Yes, both follow the law of conservation of mass. When sugar is heated, it may undergo a chemical change, such as caramelization or combustion, but the total mass of the substances will remain constant if the system is closed. Similarly, when ice melts, it undergoes a physical change from solid to liquid, but the mass remains unchanged.
Here are examples demonstrating the law:
- Heating Sugar: If you heat sugar in a closed system, the mass before and after heating should be the same, even though the sugar may change chemically.
- Ice Melting: The mass of ice before melting is the same as the mass of water after it melts since there is no loss or gain in mass, only a change in state.
This principle is foundational in Chemistry, indicating that matter is neither created nor destroyed during chemical reactions or physical changes within a closed system.
