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.

Thermodynamics A Piston-Cylinder system initially contains R-134a refrigerant at a temperature of 2.8 bar and 40 C, and its initial volume is 0.1 m3. First, heat is transferred to the system by keeping the piston constant and this process is continued until the pressure is 3.2 bar. the process is maintained by allowing the volume to change. At the end of this process, the temperature reaches 50C. Assuming the state changes as if balanced, calculate the following: a)He amount of heat transferred during constant pressure operation b)Show the state changes on the P-v diagram.
