Final answer:
Sauce burning on a stove and dry ice sublimating are both caused by heating and conserve mass; however, the former is a chemical change, while the latter is a physical change.
Step-by-step explanation:
What do the two processes of sauce burning on a stove and dry ice sublimating have in common? The correct answers would be:
- Both conserve mass: This is true because, according to the Law of Conservation of Mass, the mass of the system remains constant, regardless of the changes it undergoes, whether physical or chemical.
- Both are caused by heating: While dry ice sublimates directly from solid to gas phase when it gains heat, sauce burning on a stove is also a result of heating that leads to a chemical change where new substances are formed.
However, these processes are not strictly similar in every aspect:
- Sauce burning on a stove is a chemical change, because it produces new substances through a reaction (e.g., charred sauce components) which differs from the physical change of sublimation.
- Dry ice sublimating is a physical change because the substance (carbon dioxide) remains unchanged chemically, only the state of matter is transformed due to energy change.
Both processes do not fall under the category of solely 'physical changes' or 'chemical changes' -- they differ in this respect. Hence, Options b and d from the given choices are not correct for these scenarios.
