Before the books touched, we can think of their temperatures like this: let’s say each book was sitting on a shelf and had its own temperature based on how long it had been there. If we know the books were at different temperatures before they touched, we can imagine some were warm and some were cool.
When the two books touch, heat transfers from the warmer book to the cooler book. Just like when you hold hands with someone, your warmth will transfer to them a little bit. So, once the books start touching for a while, the warmer book will start to cool down a bit, and the cooler book will warm up a bit.
In the end, if we look at the two top books after they’ve been touching for a while, the book that was originally warmer will still be warmer than the one that was originally cooler, but not as warm as it was before. The cooler book will become warmer, but it likely won’t get as hot as the warmer book was originally. So, after some time, the top book will be warmer than it was, and the bottom book will be cooler than it was, but the temperature difference will be less than it was at the start.
