0.09 m² of fluid at .7 bar is compressed reversibly to a pressure of 3.5 bar according to a law PV"=C. The fluid is then heated reversibly at constant volume until the pressure is 4 bar; the specific volume is 0.5 m³/kg. A reversible expansion according to a law PV²=C restores the fluid to its initial condition. Calculate the mass of the fluid present, the value of n_and the net work done on or by the system and sketch the cycle on the P-V diagram.

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.
