Calorie (th) as a Unit of Energy
A calorie (th), often referred to as "thermochemical calorie," is a unit of energy defined as the amount of heat needed to raise the temperature of one gram of water by one degree Celsius at a pressure of one atmosphere. This unit is particularly significant in chemistry and thermodynamics, where it is used to quantify energy transfer in chemical reactions and physical processes.
The calorie (th) is part of the broader calorie family, which includes the kilocalorie (kcal), commonly used in nutrition to indicate the energy content of food. Understanding calories is essential for studying energy balance in biological systems, as they provide insights into metabolism and dietary energy requirements. Although the calorie has been largely replaced by the joule in scientific contexts, it remains widely used in everyday applications, particularly in the fields of diet and exercise.
