Define reversible process in physics
WebJun 30, 2024 · An isobaric process is a thermodynamic process in which the pressure remains constant. This is usually obtained by allowing the volume to expand or contract in such a way to neutralize any pressure changes that would be caused by heat transfer . The term isobaric comes from Greek iso, meaning equal, and baros, meaning weight. WebTime reversibility. A mathematical or physical process is time-reversible if the dynamics of the process remain well-defined when the sequence of time-states is reversed. A deterministic process is time-reversible if the time-reversed process satisfies the same dynamic equations as the original process; in other words, the equations are ...

WebSolution. The ice is melted by the addition of heat: Q = m L f = 50 g × 335 J/g = 16.8 kJ. In this reversible process, the temperature of the ice-water mixture is fixed at 0 °C or 273 K. Now from Δ S = Q / T, the entropy change of the ice is. Δ S = 16.8 kJ 273 K = 61.5 J/K. when it melts to water at 0 °C. WebSep 12, 2024 · When the first law of thermodynamics is applied to a cyclic process, we obtain a simple relation between heat into the system and the work done by the system over the cycle: (3.5.2) Q = W ( c y c l i c p r o c e s s). Thermodynamic processes are also distinguished by whether or not they are reversible.
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 ... WebHere Q is the energy transferred as heat to or from the system during the process, and T is the system’s temperature in kelvins during the process. If we assume a reversible isothermal process, the total entropy change is given by: ∆S = S 2 – S 1 = Q/T. In this equation, the quotient Q/T is related to the increase in disorder. Higher ...
