After completing a Carnot cycle, the entropy of the system remains unchanged, so is there any entrop

Because entropy is a function of state, the entropy of the system becomes zero, and secondly, because the cycle is irreversible, the total entropy of the system plus the environment must be greater than zero, that is, the entropy of the environment becomes greater than zero.

For a reversible cyclic process, it can be broken down into the integration of many tiny cycles, in which the entropy becomes 0. The entropy of the system is only related to the beginning and end states, not the process, so if the beginning and end states are an irreversible process.

A reversible process can be designed between the two states, and the entropy change of the irreversible process between the two equilibrium states can be obtained by calculating the integral of the heat-to-temperature ratio of the reversible process.

1. The sum of the heat and temperature quotient of any reversible cycle process is zero.

2. Entropy is the breadth property of the system, which has additivity.

3. Entropy is a function of state.

4. The heat-temperature quotient of a reversible process is not entropy, but the change of the entropy function in the process. The sum of the heat-temperature quotient of an irreversible process is less than the entropy change between the constant states of the process system.

5. Clausius inequality ds-δq t 0

Q is the heat exchanged in the actual process, and T is the temperature of the environment.

The medium sign is applied to a reversible process where the environment and the system are in equilibrium and the temperature is equal.

The unequal sign applies to irreversible processes.

The sum of the heat-to-temperature ratio of any reversible cycling process is zero, and entropy is the increment of the state function of the heat-to-temperature ratio. For a reversible cyclic process, it can be broken down into many tiny cyclic integrals. In these tiny cycles, the entropy becomes 0, so there is an irreversible cyclic process in which the entropy of the system becomes equal to zero.

In addition, because the irreversible cyclic process is irreversible, the total entropy of the system plus the environment must be greater than zero, that is, the entropy of the environment becomes greater than zero.

Firstly, the system returns to the beginning state through the cyclic process, because the entropy is a state function, so the entropy of the system becomes zero, and secondly, because the cycle is irreversible, the total entropy of the system plus the environment must be greater than zero, that is, the entropy of the environment becomes greater than zero.

Entropy is a function of state, so after going through a cycle, the entropy of the system becomes zero. Because it is an irreversible cycle, the entropy of the system is greater than zero, and the entropy of the natural environment is greater than zero.

Arbitrary reversible cycle process, the entropy of the system becomes trapped: finch shirt () aA collapse of spring is set at zero.

c.It must be negative.

d.is a function of temperature.
