Cyclic isothermal reversible workdone
WebIn (a), the process is reversible isothermal gas expansion. In this process, the amount of heat absorbed by the ideal gas is q in from the heat source at a temperature of T h. The gas expands and does work on the surroundings. In (b), the … WebAnswer (1 of 2): You will have to describe how one can have a cyclic process that is entirely isothermal in which any work is done. Draw a P-V diagram of the “cycle”. You will have …

WebConsider a cylinder with μ, moles of an ideal gas at isothermal expansion, then it reaches its final state (P 2,V 2) from initial state (P 1,V 1) Meanwhile, in the state when pressure is P and change in volume is V+dV from V, then pressure (P). dW=PdV Thus, total work done: E isothermal=∫ V 1V 2P dV ...(13.20) WebJul 20, 2024 · Consistent with prior research, we find that many students did not know that, when considering entropy in a general cyclic process (i.e., not necessarily reversible), only the entropy of the system (the working fluid) returns to the initial value.
WebSep 9, 2024 · Recognizing that the work done in a reversible process at constant pressure is wrev = − PΔV, we can express Equation 13.4.3 as follows: ΔU = qrev + wrev = TΔS − PΔV Thus the change in the internal energy of the system is related to the change in entropy, the absolute temperature, and the PV work done. The reversible expansion of an ideal gas can be used as an example of work produced by an isothermal process. Of particular interest is the extent to which heat is converted to usable work, and the relationship between the confining force and the extent of expansion. During isothermal expansion of an ideal gas, both p and V change along an is…
WebJun 27, 2024 · The so-called adiabatic legs of the Carnot cycle (isothermal-adiabatic-isothermal-adiabatic) are such processes during which there is no heat exchange at all; heat is exchanged during the two isothermal legs: absorb heat at the high temperature and release heat at the low temperature.
