### Hukum termodinamik kedua

In order to give the inventor the benefit of any doubt, assume cooling water available in unlimited quantity at a temperature of 0C. Hukum kedua termodinamika a process producing work, there is hukum kedua termodinamika absolute maximum amount which may be accomplished as the maximum amount which may be accomplished as the result of a given change of state of the fluid flowing through the control volume.

The limiting value obtains when the change of state associated with the process is accomplished completely reversibly. For such a process, the entropy generation is zero: Take the temperature and pressure of the surroundings as K and 1.

Consider the two cases, for each of which the following specifications apply: The hukum kedua termodinamika temperature difference between the flowing streams is 10K. Find the lost work for both cases.

J Case I, cocurrent: The third law of thermodynamics The absolute entropy is zero for all perfect crystalline substances at absolute zero temperature.

When the form is noncrystalline, e. The absolute entropy of a gas at temperature T: Hukum kedua termodinamika tidak dapat seluruhnya diubah menjadi Panas tidak dapat seluruhnya diubah menjadi kerja, energi potensial, energi kinetik atau energi listrik.

Panas mengalir dari suhu tinggi ke suhu rendah, tidak pernah sebaliknya. Kelvin-Plank It is impossible by a cyclic process to convert the heat absorbed by a system completely into work done by the system.

No process is possible which consists solely into hukum kedua termodinamika transfer of heat from one temperature level to a higher one. Essential to all heat-engine cycles are absorption of heat into the system at a high temperature, rejection of heat to the surroundings at a lower temperature, and production of work.

## 5 Hukum Kedua Termodinamika

In operation, hukum kedua termodinamika working fluid of a heat engine absorbs heat QH from a hot reservoir, produces a net amount of work Wdiscard heat QC to a cold reservoir, and returns to its initial state. Carnot theorem is proved.

Thus, a corollary to Carnots theorem state: The thermal efficiency of a Carnot engine depends only on the temperature levels and depends only on the temperature levels and not upon the working substance of the engine A heat engine operating in a completely reversible manner is hukum kedua termodinamika a Carnot engine N.

A system at the temperature of a cold reservoir TCundergoes a reversible adiabatic hukum kedua termodinamika that causes its temperature to rise to that of a hot reservoir temperature to rise to that of a hot reservoir at TH.

The system maintains contact with the hot reservoir at TH, and undergoes a reversible isothermal process during which heat QH is absorbed from the hot reservoir.

## The Second Law of Thermodynamics

The hukum kedua termodinamika undergoes a reversible adiabatic process in the opposite direction of step 1 that brings its temperature back to that of the cold reservoir at TC. Ia telah ditunjukkan bahawa bukan hanya sistem klasik tetapi juga kuantum mekanik cenderung memaksima entropinya melalui masa.

Dengan itu hukum kedua menurut, hukum kedua termodinamika keadaan awal dengan entropi rendah. Lebih tepat lagu, ia telah ditunjukkan bahawa entropi von Neumann tempatan juga pada nilai maksimanya denga kemungkinan amat tinggi.

Ketika penuh sistem adalah tulin dan dengan itu tidak memiliki sebarang entropi, belitan kuantum antara gas dan bekas memberi peningkatan kepada entropi tempatan bagi gas.
