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.

A certain gas with One kilogram of mass, 100 kPa and 45°C is compressed adiabatically until the volume is minimizes to one sixteenth of its original rate. So, heat is further at persistent pressure until the temperature is 1450 °C. The gas is then extended adiabatically till to its initial volume is got and lastly it is cooled at constant volume till the original state of 100 kPa and 1450 °C is reached.
