Q:) A piston-cylinder device initially contains 0.5 kg of air at 1 MPa and 400°C. The air is first compressed Polytropically with a Polytropic exponent of (K = 1.4) to 4 MPa, then expanded isothermally to the initial pressure, and finally compressed at the constant pressure to the initial state. Draw the PV diagram of the cycle and then determine: I The boundary work of the entire cycle (W). II. Internal energy change (AU) during the polytropic expansion. Heat released (Q) during the isobaric process. III.

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.
