To accurately answer your question regarding the temperatures of the four books and the comparison after they touch, I need to clarify a few points based on typical scenarios involving heat transfer.
Before the books touch, the temperatures of the four books vary based on factors such as their environment, material, and how long they've been out. We can presume that if the books have been in a similar environment for the same amount of time, their temperatures would likely be close to the same. However, if some were exposed to sunlight or heat sources while others were not, there would be differences.
Once the books are placed in two stacks and they begin to touch, heat transfer occurs due to conduction, where heat moves from the warmer object to the cooler one until thermal equilibrium is reached.
Assuming the two top books in each stack initially have different temperatures, after they have been touching for a while, the temperatures will equalize. This means that the two top books will have similar temperatures that fall somewhere between their initial temperatures, depending on how warm or cool each book was before contact.
To summarize:
- Before touching, the temperatures of the four books could vary based on their environment or exposure to heat.
- After touching for some time, the two top books will reach a thermal equilibrium, resulting in them having similar (or equal) temperatures.
