### thermodynamics Laws,Definition, Equations Britannica

Thermodynamics,science of the relationship between heat,work,temperature,and energy.Thermodynamics deals with the transfer of energy from one place to another and from one form to another.The key concept is that heat is a form of energy corresponding to a definite amount of mechanical work.What Are Some Everyday Examples of the First Second Laws The laws of thermodynamics dictate energy behavior,for example,how and why heat,which is a form of energy,transfers between different objects.The first law of thermodynamics is the law of conservation of energy and matter.In essence,energy can neither be created nor destroyed; it can however be transformed from one form to another.Use of First Law of Thermodynamics in Adiabatic Process Use of First Law of Thermodynamics in adiabatic process.The process in which heat in a system remains constant but pressure and the volume change is called adiabatic process.In thermodynamics,an adiabatic process is one that occurs without transfer of heat or matter between a thermodynamic system and its surroundings.In an adiabatic process,energy is transferred to its surroundings only as
