Thermodynamics

Enthalpy diagrams are a representation of the relative internal energy of a system before and after a reaction. Horizontal lines are drawn to show the…

The heat absorbed or evolved by a reaction depends on the conditions under which it occurs, such as pressure. Thus instead of the term “heat”,…

Heat can be defined as the energy that flows into or out of a system because of a difference in temperature between the system and…

All chemical reactions obey the First Law of Thermodynamics (also known as The Law of Conservation of Energy). This law states that the “Energy may…

Thermodynamics is the science of the relationship between heat and other forms of energy. Thermochemistry is the area of Thermodynamics related to the heat changes…

Reversible process: A thermodynamic process in which any sort of change of a working substance in the external condition, starting from a given initial can…
