Then the com­plete external effect is raising up the body, so the system is doing thermody­namic work. When the work is done by the system, then it is taken as + ve, and when the work is done on the system, it is taken as - ve.

The branch of science called thermodynamics deals with systems that are able to transfer thermal energy into at least one other form of energy (mechanical, electrical, etc.) or into work Why did we talk about thermodynamics? Because the refrigerator is formed by the second law of thermodynamics. The second law of thermodynamics is talked about the quality of energy. It states that the energy is transferred or transformed, more and more of it is wasted. It also states that there is a natural tendency of any isolated systems to degenerate into a more disordered state What is Thermodynamics? Let us break the word thermodynamics into two words, thermo and dynamics. 'Thermo' stands for heat while 'dynamics' is used in connection with a mechanical motion which involves 'work'.Therefore, Thermodynamics is the branch of physics that deals with the relationship between heat and other forms of energy Thermodynamics is the branch of physics which deals with the study of relation b/w heat,temperature,work and energy.

The laws of thermodynamics govern the direction of a spontaneous process, ensuring that if a sufficiently large number of individual interactions are involved, then the direction will always be in the direction of increased entropy.

Consider a system in contact with a heat reservoir during a reversible process. If there is heat absorbed by the reservoir at temperature , the change in entropy of the reservoir is .In general, reversible processes are accompanied by heat exchanges that occur at different temperatures of the system. In thermodynamics, we call it the internal energy, U of the system, which may change, when • heat passes into or out of the system, • work is done on or by the system, ••• matter enters or leaves the system. These systems are classified accordingly as you have already studied in section 6.1.2.

Thermodynamic work is the amount of work a system does on the environment, for example, by the heat-induced expansion of a gas pushing a piston outwards. This is an example of how heat energy in a thermodynamic process can be converted into mechanical energy, and it is the core principle behind the operation of many engines. In turn, heat or thermal energy is the thermodynamic energy transfer. The 1st Law of Thermodynamics tells us that energy is neither created nor destroyed, thus the energy of the universe is a constant.However, energy can be transferred from one part of the universe to another. To work out thermodynamic problems we will need to isolate a certain portion of the universe, the system, from the remainder of the universe, the surroundings Thermodynamics - Thermodynamics - Open systems: Most real thermodynamic systems are open systems that exchange heat and work with their environment, rather than the closed systems described thus far. For example, living systems are clearly able to achieve a local reduction in their entropy as they grow and develop; they create structures of greater internal energy (i.e., they lower entropy.

THERMODYNAMICS CONCEPT. Thermodynamics is the study of the relationships between heat, work, and energy. Though rooted in physics, it has a clear application to chemistry, biology, and other sciences: in a sense, physical life itself can be described as a continual thermodynamic cycle of transformations between heat and energy Work function (thermodynamics) The thermodynamic function better known as the Helmholtz energy, A = U - TS, where U is the internal energy, T is the thermodynamic (absolute) temperature, and S is the entropy of the system. At constant temperature, the change in work function is equal to the maximum work that can be done by a system (ΔA = w max). See Free energ Work done by a thermodynamic system depends not only upon the initial and final states of the system but also depend upon the path followed in the process.
