Answer:
Explanation:
A substance with a high specific heat, such as the water in Figure 9, heats up and cools down slowly because a much larger quantity of heat is required to cause its temperature to rise or fall by the same amount. Matter can change from one state to another when thermal energy is absorbed or released.

A well tested explanation of a natural phenomenon
Explanation:
A scientific theory is an explanation of a natural phenomenon which has been drawn from a well tested observation.
Theories are products of repeated scientific experiments. When a hypothesis otherwise known as a "scientific guess" survives a lot of scrutiny, we can elevate it to the status of a theory. Most theories starts off from simple observations. These observations can further spark series of experiments in such a field and a scientific guess proposed. Further testing and experimenting would now lead to a theory.
