A piston-cylinder assembly contains 5 kg of saturated water vapor at a pressure of 3 MPa. At the end of the change of State, heat is given out of the cylinder at constant pressure until the water vapor is completely condensed, so that the liquid remains saturated at a pressure of 3 MPa in the wipe - dirde. During this state change, what happens to the fog - min entropy change?

Entropy

In physics, entropy means the amount of disorder or the degree of randomness associated with a thermodynamic system. The system is not self-organized when the entropy of the system is high. For instance, when a system is at an elevated temperature, its molecules are in random motion, vibrating and colliding with each other. During this scenario, the probability of finding a molecule at a particular place twice, is low. Under this circumstance, the system can be said to be in a high entropy.
