In a thermodynamics problem, the surroundings, or environment, are anything not part of the system. They are separated from the system by a real or imaginary boundary. Together with the system, they make up the universe.
The surroundings do not contain any processes of interest. However, they can usually exchange energy and sometimes even matter with the system, influencing the processes that occur there.
Thermodynamics is the study of energy, its conversions between various forms such as heat, and the ability of energy to do work.
Zeroth law: A fundamental concept within thermodynamics, however, it was not termed a law until after the first three laws were already widely in use, hence the zero numbering.
Portions of the boundary between the open system and its surroundings may be impermeable and/or adiabatic, however at least part of this boundary is subject to heat and mass exchange with the surroundings.
Thermodynamics (from the Greek thermos meaning heat and dynamis meaning power) is a branch of physics that studies the effects of temperature on physical systems at the macroscopic scale.
Statistical mechanics is the underlying theory that sustains thermodynamics; it provides a way to predict the entropy of a thermodynamic system, based on the statistical analysis of the thermal fluctuations that the system experiences in its particular microstates.
However, the dependence of any one of these four thermodynamic potentials cannot be expressed in terms of the thermodynamic parameters of the system without knowledge of the interaction potentials between system components, the quantum energy levels and their corresponding degeneracies, or the partition function of the system under study.
