Final answer:
The temperature changes observed on the stove and in the refrigerator are different. On the stove, the temperature increases due to the heat source, while in the refrigerator, the temperature decreases as heat is removed.
Step-by-step explanation:
When something is put on the stove or in the refrigerator, the temperature changes are different from the temperature changes observed in investigations because of the different purposes and mechanisms involved.
On the stove, the heat source increases the temperature of the object or substance being heated. This can lead to reactions, such as cooking or boiling, where the temperature change is significant and can be observed.
On the other hand, the refrigerator cools the object or substance by removing heat, which slows down or prevents chemical reactions and bacterial growth. The temperature change in the refrigerator is a decrease, and the object or substance remains at a lower temperature compared to its initial state.
