We often automatically equate heat with temperature to such a degree that we may not take the time to consider what heat really is. Heat refers to the energy that is transferred from one body to another that is at a lower temperature. This transfer occurs often without us knowing it, but it is ever-present and crucial to all life. This volume examines the basics of heat and the related concept of temperature. Detailed diagrams help illustrate such concepts as specific heat capacity and latent heat. Clear text explains the difference between conduction, convection, and radiation, as well as emitters, absorbers, and more.
