Compare the example of a dry and wet thermometer. Check out the study material. Answer the question.
Minu kuiva ja märja termomeetri näidud erinesid maksimaalselt | ∘C võrra. |
In the experiment, the wet thermometer cools noticeably. The reason is that it takes energy to evaporate water. If there are no other sources of energy, this manifests itself as water cooling. The water, in turn, also cools the thermometer to which it is attached.
A number of parallels can be drawn from here on how water can cool things by evaporation. These possibilities are mentioned in the following task.
