In thermodynamics, a reversible process is a process, involving a system and its surroundings, whose direction can be reversed by infinitesimal changes...

In thermodynamics, an irreversible process is a process that cannot be undone. All complex natural processes are irreversible, although a phase transition...

Reversible computing is any model of computation where every step of the process is time-reversible. This means that, given the output of a computation...

In thermodynamics, a quasi-static process, also known as a quasi-equilibrium process (from Latin quasi, meaning ‘as if’), is a thermodynamic process that...

is path independent for reversible processes. So we can define a state function S called entropy, which for a reversible process or for pure heat transfer...

law of thermodynamics is a formulation of the law of conservation of energy in the context of thermodynamic processes. For a thermodynamic process affecting...

In thermodynamics, an isochoric process, also called a constant-volume process, an isovolumetric process, or an isometric process, is a thermodynamic process...

isothermal process, an adiabatic process transfers energy to the surroundings only as work and/or mass flow. As a key concept in thermodynamics, the adiabatic...

In thermodynamics, an isobaric process is a type of thermodynamic process in which the pressure of the system stays constant: ΔP = 0. The heat transferred...

Classical thermodynamics considers three main kinds of thermodynamic processes: (1) changes in a system, (2) cycles in a system, and (3) flow processes. (1)...

In classical thermodynamics, entropy (from Greek τρoπή (tropḗ) 'transformation') is a property of a thermodynamic system that expresses the direction or...

work done by the system during the whole of the reversible process. The first law of thermodynamics can then be expressed as d U = δ Q − P d V . {\displaystyle...
