WebThe entropy of a given mass does not change during a process that is internally reversible and adiabatic. A process during which the entropy remains constant is called an isentropic process, written = or =. Some examples of theoretically isentropic thermodynamic devices are pumps, gas compressors, turbines, nozzles, and diffusers.. … WebAug 8, 2024 · Correct answer: Entropy. My answer: Compressibility. My Reasoning : Z = P V n R T. In adiabatic T V γ − 1 = constant. Therefore, T ∝ 1 V γ − 1. γ − 1 is greater than zero always. So we can say is volume increases, temp decreases. Therefore Z should increase as its numerator increases and denominator decreases. daylight\\u0027s a6Webadiabatic free expansion of an ideal gas, a more rigorous development of the statistical interpretation of entropy would lead us to the same conclusion. 3.

WebJan 5, 2009 · 4. There are two compartments, each has half volume of the total volume, separated by an insulating partition. The whole setup is adiabatic. n mole of a monatomic gas with temperature T1 and pressure P in the left while in the right m mole of monatomic gas with termparture T2 and pressure P there. Now remove the partition so two gas mix, … WebEntropy is a measure of the disorder of a system. Entropy also describes how much energy is not available to do work. The more disordered a system and higher the entropy, the less of a system's energy is available to do work. Although all forms of energy can be used to do work, it is not possible to use the entire available energy for work.
