Thermal Physics

This introduction to thermal physics aims to combine both the macroscopic and microscopic approaches. To avoid confusion, they are first introduced separately, and then a number of selected topics are examined from both points of view. In this way the strengths and weaknesses of the different methods can be studied and the text will thus give an introduction which can be the basis for further studies of the properties of matter, whether from a thermodynamic or from a statistical point of view.
