Introduction

Many of the most significant developments in physical chemistry and chemical engineering in the past have been based on contributions made by physical properties of substances. Heat capacity is one of the most essential physical properties. It is the quantity of heat required to raise the temperature of a unit mole or mass of a substance or a mixture of substances by 1 °C. 

This reference book provides heat capacity data of more than 200 fluids at 1 atm and up to 1000 °C. The data has been collected by the author over more than 10 years. The fluids in this book are arranged by their chemical formulas to provide ease of use.
