Thermochemistry vs. Thermodynamics

Thermochemistrynoun

The study of the thermodynamics of chemical reactions.

Thermochemistrynoun

That branch of chemical science which includes the investigation of the various relations existing between chemical action and that manifestation of force termed heat, or the determination of the heat evolved by, or employed in, chemical actions.

Thermochemistry

Thermochemistry is the study of the heat energy which is associated with chemical reactions and/or physical transformations. A reaction may release or absorb energy, and a phase change may do the same, such as in melting and boiling.

Thermodynamicsnoun

(physics) The science of the conversions between heat and other forms of energy.

Thermodynamicsnoun

The science which treats of the mechanical action or relations of heat.

Thermodynamicsnoun

the branch of physics concerned with the conversion of different forms of energy

Thermodynamics

Thermodynamics is a branch of physics that deals with heat, work, and temperature, and their relation to energy, radiation, and physical properties of matter. The behavior of these quantities is governed by the four laws of thermodynamics which convey a quantitative description using measurable macroscopic physical quantities, but may be explained in terms of microscopic constituents by statistical mechanics.
