WebEntropy is a thermodynamic property that measures the degree of randomization or disorder at the microscopic level. The natural state of affairs is for entropy to be produced by all processes. If a system has a temperature T (in absolute scale) and a small quantity of heat ΔQ is given to it, we define the change in the entropy of the system as: Webreversibility, in thermodynamics, a characteristic of certain processes (changes of a system from an initial state to a final state spontaneously or as a result of interactions with other systems) that can be reversed, and the system restored to its initial state, without leaving net effects in any of the systems involved. An example of a reversible process …

WebA reversible process is a process that can be reversed to obtain the initial state of the system whereas an irreversible process is a thermodynamic process that cannot be reversed to obtain the initial state of a system. In reversible process, infinite change occurs in the system, and in the case of the Irreversible process, finite changes ... WebAdiabatic Process Derivation. The equation for an adiabatic process can be derived from the first law of thermodynamics relating to the change in internal energy dU to the work W done by the system and the heat dQ added to it. dU=dQ-dW. dQ=0 by definition, Therefore, 0=dQ=dU+dW. The work done dW for the change in volume V by dV is given as PdV. lanterna jardim
