Thermal science, also known as thermophysics, is the science of thermal phenomena (i.e., physical phenomena related to temperature). Thermal science is generally divided into two parts: thermodynamics and statistical mechanics, the former being a macroscopic theory based on experiments, and the latter being a microscopic theory based on quantum mechanics and mathematical statistics. Thermal science was developed only from the end of the 18th century and focuses on the study of energy transfer between work and heat. Here work is defined as the inner product of force and displacement, while heat is defined as the transfer of energy caused by the difference in temperature at the boundary of a thermal system.

In the present book, thirteen typical literatures about Thermal Science published on international authoritative journals were selected to introduce the worldwide newest progress, which contains reviews or original researches on Thermal reactions, Efects of iron spin transition, Enthalpies of formation and standard entropies, steady-state evaporation of water, Thermal stability, ect. We hope this book can demonstrate advances in Thermal Science as well as give references to the researchers, students and other related people.
