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.

Consider an engine operating on the following cycle using 4 moles of neon as the working fluid. Starting at a pressure of 5 atm and a volume of 2m3, the gas expands isothermally to a volume of 3m3, then is compressed isobarically back to 2m3, and finally returns isochorically to the initial state. What is the efficiency of this engine?
