Find the entropy production and determine if the cycle operates irreverisbly, reverisbly, or impossibly. A refrigeration cycle operates between the freezer compartment at 268K and the ambient air at 295K. The rate of heat transfer from the freezer compartment is 8000 kJ/h and the power input for the cycle is 3200 kJ/h. Determine the entropy production for this cycle in kJ/K·h (do not convert h to s). Enter the answer without units, but with a minus sign if applicable. This cycle operates     irreversibly     reversibly     impossibly.

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.
