Examine the situation depicted in the picture. Familiarize yourself with the concepts of thermal equilibrium. Answer the question.
The picture shows an empty classroom. However, it is not completely empty - there are a large number of smaller and larger items on the tables and cabinets.
What can we say about the temperature of these objects? If someone asked us to measure the temperatures of all the objects in the classroom, what would be the smartest answer?
In fact, we already tried to measure the temperatures of all objects in the classroom. At that time, we got the following table as a result:
| The body | Temperature |
| The atmosphere in the classroom | |
| Table top | |
| Palm | |
| Aluminum test piece |
What would we be able to tell about the temperatures of all the objects in the classroom if we measured the temperature of just one object? We already know the concepts of heat transfer and thermal equilibrium.
