When you pick up a book are energy from your hand to the book?

When you pick up a book, some energy from your hand will definitely be transferred to the book. This energy transferred is mainly in the form of heat. When your hand comes into contact with the book, the molecules in your hand and the molecules on the surface of the book start to interact with each other. Due to these interactions, the average kinetic energy of the molecules on the surface of the book would slightly increase which results in a very little increase in the internal energy of the book. This means that the temperature of the book will rise by an insignificant amount. Additionally, when you are holding the book, some mechanical energy in the form of the gravitational potential energy is also transferred to the book but that too would be quite negligible.
