Thermodynamics Is A Branch of

Thermodynamics is a branch of physics that deals with heat, work, and temperature, and their relation to energy, radiation, and physical properties of matter. It describes the behavior of these quantities through the four laws of thermodynamics and can be explained by statistical mechanics. Thermodynamics applies widely in science and engineering, especially in fields like physical chemistry, chemical engineering, and mechanical engineering. Historically, it developed from efforts to increase the efficiency of early steam engines.

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. Thermodynamics applies to a wide variety
of topics in science and engineering, especially physical chemistry, chemical
engineering and mechanical engineering, but also in other complex fields such as meteorology.
Historically, thermodynamics developed out of a desire to increase the efficiency of early steam
engines, particularly through the work of French physicist Nicolas Léonard Sadi Carnot (1824)
who believed that engine efficiency was the key that could help France win the Napoleonic
Wars.[1] Scots-Irish physicist Lord Kelvin was the first to formulate a concise definition of
thermodynamics in 1854[2] which stated, "Thermo-dynamics is the subject of the relation of heat
to forces acting between contiguous parts of bodies, and the relation of heat to electrical
agency."
The initial application of thermodynamics to mechanical heat engines was quickly extended to
the study of chemical compounds and chemical reactions. Chemical thermodynamics studies the
nature of the role of entropy in the process of chemical reactions and has provided the bulk of
expansion and knowledge of the field.[3][4][5][6][7][8][9][10][11] Other formulations of thermodynamics
emerged. Statistical thermodynamics, or statistical mechanics, concerns itself
with statistical predictions of the collective motion of particles from their microscopic behavior. In
1909, Constantin Carathéodory presented a purely mathematical approach in
an axiomatic formulation, a description often referred to as geometrical thermodynamics.
